Lightroom 4: Assertion Failed message when opening a catalog

I have an assertion failed message pop up when I try to open one specific catalog in LR 4, I have gone and cleared the preference file and was able to open other catalogs. I guess my question is, is that catalog dead or is there a way I can salvage it?

Thank you,
Doug

Are you possibly trying to open an image rather than a catalog?

Does Lightroom give you any more details other than "Assertion Failed"? Do you have any 3rd party plug-ins/add ons installed in your version of Lightroom?

I now have a problem like this!
I simply tried creating a new catalog. It closed the old catalog (like it does when changing catalogs) then throws a small popup window that says "assertion failed".
Then when you try to restart LightRoom it gives you the attached error screen

What happens when you choose a different catalog or try creating a new one?
Do you get this same error message Greg?

Trying clearing your preference file. Lightroom will rebuild it on startup. You can find the location of the preference file documented here:

Same thing...
Now then interesting twist on the game....
- I deleted the prefs. I deleted all the preview data. STILL happens.
- I deleted the prefs and data again... BUT this time I moved ALL movie files that had been imported via lightroom (by accident with the card imports)... (there needs to be a setting to checkbox what file types your want the import process to consider, so you can basically IGNORE videos if you want to. I use another catalog and editing system to manage my videos. Anyway, once all the videos were gone... it worked for a really short time, like 3 or 4 starts of LR4.
- IF I can get out of the error cycle, and create a new cat on the C: drive... it works like a dream.

Keep in mind that leading up to this, that I had the following configuration:
AMD 9550 Quad Core, 6GB RAM, ATI Radeon HD 6600 2GB GDDR5
C: - 2TB - Apps and OS
D: - DVD
E: - 1TB - Videos, Music, Raw Audio for Video
F: - 1 TB - Photos and where LR imports to
NAS - Synology 1511 loaded with 5 2TB drives

This issue started happening AFTER the following:\
- I added the G: drive (a new 3TB drive for photos)
- I opened LR4 and created NEW Catalogs on the G: drive and IMPORTED the old catalogs off the F: drive. ... note: I created new catalogs for each year 2000-2004; then 06, 07, 08, etc. to 12 and finally 13.
- When I got to 12, the import failed... when going back and reviewing and trying to do it again, I watched it... it failed when it encountered a video file.
- I tried 13... the import ran for a while, then failed when it got to a video file as well.
- I removed the video files to the E: drive and tried the imports again... and they worked.
- I took the old F: drive out of the machine after having migrated everything over to the new drive.
When the F: drive disappeared out of the equation... that's when these problems all started happening.

I am about to back up EVERYTHING to my NAS and blow the WHOLE box away, re-image the OS and re-install everything from scratch to get a clean install from the ground up.

At this time, LR is the ONLY application that is acting up.

One other note for the record.
The video files that were encountered, came from the following 3 cameras:
- Canon Powershot A590
- Canon S100
- Canon 60D

LR4 also started having a problem when I got my 60D and the JPG + RAW files started being a lot bigger.

Thanks for adding all of this great info Greg.

It does seem like some of the video files are causing the catalog to hiccup when imported.

Since it seems that after removing the video files from the folders LR seems to operate just fine.
It might be good if we could get a couple of those video files that are causing you trouble to see if we can reproduce in-house.

The last suggestion would be to install LR 4.4 if you haven't yet already to see if it provides some fixes that may help you out.

Would you be able to share some video files with us? If you can put them on Dropbox or some other share, you can share it with me directly, petgreen [at] adobe [dot] com (yep, the email addy is petgreen not petegreen... [sic] is appropriate)

thanks!
