mythfrontend.real crashed with SIGSEGV

[Sven Sprengel]

Binary package hint: mythtv

Earlier I already sent a bug report of this, assuming that it is related to the fglrx driver. Now this one is with the ati driver.

I too am seeing this issue, it should also be noted that the FE doesn't die when this happens, just produces the above crash report. I am using x86_64 however. Else everything is the same.

Nick please file a bug with tour crash report. It may look very
similar, but possibly still different.

Howdy! This ticket is quite old and the mythtv developers upstream have stopped focusing on 0.21 based reports in preparation for a 0.22 release later this year. Can you please try to see if this bug is reproducible on 0.22? If it is, we can try to forward this bug upstream to get the right eyes focused on it - otherwise we need to close it.

We have builds of mythtv 0.22 available on a PPA to test. Please follow the directions at http://mythbuntu.org/auto-builds to enable them.

WARNING: If you intend to revert back to 0.21 after testing, you will need to back up your database before upgrading.

    Thanks!

Howdy, we really do appreciate you opening this ticket to help improve Mythbuntu, but it needs to be closed for a number of reasons. The biggest one is that the MythTV developers have turned their efforts to the next version (0.22) and beyond and are no longer fixing bugs on 0.21.

The Mythbuntu team has builds of MythTV 0.22 available on a PPA if you are interested in upgrading. Please follow the directions at
http://mythbuntu.org/auto-builds to enable them. Please do not let the closing of this ticket dissuade you from opening a new ticket if this (or any other) problem occurs with 0.22.

WARNING: If you need to have the ability to revert back to 0.21, you will need to back up your database before upgrading since a 0.22
database can not be downgraded.

   Thanks!
