[mythtv] Frontend Crash

Tue Jan 23 22:54:21 UTC 2007

Mythfrontend is crashing before displaying the main menu.

I have included a backtrace and am posting on myth-dev as suggested in 
the svn webpage.  (Should a I open a ticket in trac?)

I had a hard drive crash and so when replacing the drive I decided to 
upgrade the  distribution from  Ubuntu Breezy to Ubuntu Edgy.  I used 
standard ubuntu repositories and generated a build environment using 
apt-get build-dep mythtv.

I downloaded svn 12469 (as this machine is a frontend and the backend is 
running this version from svn).

The compile completed successfully.  I installed, but mythfrontend 
crashed before displaying the main menu.  I then re-installed myth from 
a backup I had prior to the hard disk crash, compiled when the  PC was  
running Breezy.  There appears to be no problems with this and 
mythfrontend runs without error.

I guess the problems lies with some Edgy libraries, but I'm not sure 
where to start looking.

My version of gcc is:
gcc (GCC) 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)
