Public bug reported:

Mangler "seems" to stay up longer if I do not use it to transmit my
voice, but use it to only listen, though it does still crash.  Crashes
happen 1-5 times an hour, most often when I key to speak, but not
always.  Sometimes the Mangler window 'grays out' and it will state that
it has crashed, ask if I want to leave it closed or relaunch it, other
times Mangler will simply close on its own.  Sometimes it knows it
crashed and says so very quickly, other times it will say nothing until
I click to close it, when I click to close it, it does not always pop up
the Leave Closed/Relaunch dialog box.

Text from the console from different crashes:

I have tried using both ALSA and Pulse, both crash at roughly the same
rate.  I ran Memtest 86+ for twelve passes, no errors.

I am not a trouleshooter, programmer, scripter, or otherwise tech-type
person, but if you give me clear, step by step instructions, I will be
more than happy to follow them in order to provide more information.
