gdb says "no debugging symbols found". I did compile digiKam with the 
Gentoo "debug" use flag, but that apparently was the wrong thing to do 
(https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces).

Anyway, fwiw, here's the (probably worthless) relevant gdb output, after 
going through and removing all except the problem XCF file (so as to not 
generate a ton of exceptions from digiKam not being able to read various 
embedded exif information in XCF files):

Continuing.


####### Now moving on to other files that throw exceptions but don't 
cause digiKam to hang, I seem to have missed removing a few XCF files:

and etc.

Best,
