[mythtv-users] Channel scan does not work

[Andrew Junev]

Hello All,

I was using MythTV with two DVB-S tuners for quite some time now.
Today I tried to scan for new channels and ... it didn't work. I ran
mythtvsetup, went to Channel Editor, selected Transponder Scan
(tuned), put the data of a transponder and then clicked Next - the
mythtvsetup window just closed. In the terminal output I see the
following error:

Connected to database 'mythconverg' at host: localhost
mythtvsetup: xcb_lock.c:77: _XGetXCBBuffer: Assertion `((int) ((xcb_req) - (dpy->request)) >= 0)' failed.
Aborted


I tried it with different transponders, different tuners - all the
time it was the same. Here's some info about my system:

# uname -a
Linux mythbackend 2.6.26.6-49.fc8 #1 SMP Fri Oct 17 15:59:36 EDT 2008 i686 i686 i386 GNU/Linux

I seem to have the latest mythtv version availble in the repositories.
Any ideas on what the problem might be?
