Comment 2 Dave Malcolm 2010-01-04 18:24:38 UTC 
Thank you for reporting this bug.

How reproducible is this problem?  If you run the program from a terminal, is an error message printed?

What version of smolt-gui do you have installed?

Looking at the backtrace, it looks like the problem occurred in thread #1 in QApplicationPrivate::isBlockedByModal(QWidget*), though thread #2 also appears to be talking to the X server, whilst cleaning up PyQt; this happens when the application is exiting.

Reassigning component from "python" to "smolt", though it may be a PyQt issue.
Comment 3 Dave Malcolm 2010-01-05 16:23:43 UTC 
Jim sent me a direct email in which he indicated that this segfault is happening when run as a non-root user, but works when run via sudo; hopefully he won't mind me quoting his email here; I replaced the real UID with "THE_REAL_UID" below in case of privacy concerns:

[jim@localhost ~]$ /usr/bin/smoltGui
Unable to save UUID, continuing...
Your UUID file could not be created: [Errno 13] Permission denied:

Comment 4 Mike McGrath 2010-01-05 16:40:23 UTC 
Ok, i see what is going on here but I'm not quite sure on what to do to fix it.  Basically /etc/smolt/hw-uuid doesn't get created until the first smolt run, which normally happens at firstboot.  If not then it has to be run as root first to generate that file since we don't want normal users creating that file.  I'll think on what to do about this some.
