My / partition filled up recently and that was 15gb of free space. I tracked it down to a 6gb mythbackend.log file. In it is a million times: QWaitCondition: cannot wait on recursive mutexes

Is this going to be fixed soon? I was going to update and upgrade using Mythbuntu auto-builds but I couldn't as my / partition was full. WIll try now and hope that's fixed.

Oh, currently running this version of mythtv: 0.23.0+fixes24158-0ubuntu1

With a debug build of mythtv (or debug packages installed) please run this:

QT_FATAL_ASSERT=1 gdb --args mythfilldatabase [any args you normally use]
thread apply all bt

and attach the output, the second two lines are to be typed into the gdb shell. The first to start execution and the second after the first "cannot wait..." occurs.

This will pinpoint exactly which mutex is causing the problem.
