HI!
I am not sure, if bugreports are wanted this way, but this is what I
understand from the docs.
I have a reproducable crash of mythbackend 0.14.
I am running it in a VMware with Fedora Core 1 with no capture cards
defined (just trying out MythTV in VMware before doing the real thing).
I have the crash with the ATrpms version and with MythTV self-compiled.
The crash occurs every time at the 1st click after mythbackend started
in MythWeb. This means, I start mythbackend, click somewhere in MythWeb
and mythbackend segfaults. When I restart mythbackend, MythWeb completes
the action from the last click. Another click and mythbackend crashes
again. So it's not that MythWeb does not work at all.
Attaching the gdb stacktrace.
Thomas
