Created an attachment (id=26880)
 --> (http://bugs.freedesktop.org/attachment.cgi?id=26880)
file which caused the new crash

I'm not sure if the file in the previous attachment caused the crash (as I
said, they're quite random). However, I just got another crash, with the
current version of the same file. Here's the backtrace (which looks similar to
the previous one):
Program received signal SIGABRT, Aborted.
