Lightroom 5 Crashes Randomly and Frequently (Windows)

Lightroom 5 crashes randomly and frequently during flagging and editing. There's nothing I can really do to reproduce any specific crashes. It happens on catalogs both imported from LR4 and new catalogs created by LR5. All I do to induce it is by performing normal editing procedures for a while. Then it chokes up for a few seconds and crashes. This happens during both the flagging process and the actual editing process.

Yesterday I searched this topic and found an issue people were having which was solved by resetting their preferences. For me, this actually reduced the frequency of the crashes a little bit, but they still occur often enough to seriously disrupt my workflow. Are there crashdumps I can upload to help you guys solve it? Is anyone else having this issue?

I am using Windows 7 Ultimate (64-bit) on Core i7 3770 using 16GB RAM. Someone told me to use the Adobe Crash Reporter, but I find no such program on my computer, nor a corresponding download on the internet. Here are the "problem details" pasted from one of the crashes.
