Directly after opening, Digikam shows thumb previews for up to 5 seconds then crashes. Crash log below. If there's way I can make a more verbose output, please reply to this bug report so I can do that. I checked the sqlite db and it doesn't seem corrupt.

This might be related to the problem that I am having. At the moment I can't access the main, root directory in the album view. As usual, the thumbnails momentarily appear before sorting themselves into my chosen order (descending), but then it segfaults. I've had a bit of intermittent crashy behaviour since I changed camera to the Olympus. The folder in question contains 12,000+ files of Olympus (.orf), Canon (.cr2), Panasonic (.rw2), png, jpg, wav, mov, idx, xmp (from Darktable) type. "P7012188_v2.PNG.xmp" is an example of one of the filenames that Darktable has generated. I have just tried unchecking all of the optional information in the Album View section of the settings, but it hasn't made a difference. I am also on 4.3 from the PPA on Kubuntu 14.04. As far as I can see, 4.2 could open the folder, but as I say, things have been a bit crashy ever since I got the Olympus earlier in the year. Crash report below. Let me know if there's anything you'd like me to try.
