I run a program (Cadence IC6, which is Qt-based) on a remote machine
through SSH with X11 forwarding.
After updating my client machine from Fedora17 to Fedora19 64-bit (X
version is 1.14.2-9, I believe - or please advice how I can check), I get
some errors when running the program.
Here is a transcript of parts of the log:

Also it is reflected in the dmesg of the server:
"libSelect[27710]: segfault at 0000000000000000 rip 00000000081db391 rsp
00000000ffba5380 error 4"
Well, any idea why I get these errors? And how I can debug or get rid of
them? I assume the problem is either Qt- or X-related, but honestly I don't
know much of these things.
Can it be a bug in X? Notice, that everything worked fine, when I was using
Fedora 17, so a change in Fedora 19 (X or Qt) provoked the error. Also
notice, that I'm not a developer and have close to no insight into X (might
be obvious from the above:)).
Any suggestions will be appreciated.
FYI, I also posted here (several days ago - still no answers):
