Performous hangs on the main screen

[Lucio Crusca]

Binary package hint: performous

I launch performous and the main screen shows up. I get no sound here, but the real problem is that it occasionally hangs if I press one of the keys S or Q (Start, Quit). Only the C and P keys (Configure and Practice) always work as intended.

Sometimes I'm able to practice a bit, but then it's almost a sure bet it will hang on a key press in the main menu.

Once hung, xkill does not seem to kill it either, it just closes the window, but the performous process is only sensible to a brute kill -9 or other uncaught signals.

If I run performous from the shell I get the following output:

$ performous

and the last lines repeat until I kill performous.

The front() on empty container problem has been fixed in performous 0.3.1. The hang on exit is probably due to a bug in the gstreamer driver, which is not tested properly. Can you test if this still happens in 0.3.1 or 0.3.2? If it does, run gdb performous, enter command run and make the program hang (e.g. by exiting it). Then hit Ctrl+C to break the program in gdb and get us the backtrace of each thread.

(gdb)thread 1
(gdb)bt
...
(gdb)thread 2
(gdb)bt
... and so on, until there are no more threads (around 8 is the last one).

In particular, we are interested on the two threads where the backtrace says anything about gstreamer.

Tried Performous 3.2: it works, e.g. it does not hang and (consequently) it exits normally when the window closes.
