--- Comment #1 from Michael Reed <mike at unmusic.co.uk> ---
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.

Backtrace of the crash I experienced:

Application: digiKam (digikam), signal: Segmentation fault
