Bug#724502: kmix: KMix crashes when drag&drop channel
Package: kmix
Version: 4:4.10.5-1
Severity: important
Dear Maintainer,
My sound card is "Creative Labs SB Live! EMU10k1 (rev 0a) / Creative Labs
SBLive! 5.1 Digital Model SB0220" backed by kernel module snd_emu10k1.
It has a switch "Mic Boost +20db". When I add it to the list of used channels
and try to drag it KMix crashes.
Possibly I need to build kmix-dbg from Debian source package. Please adwise if
it will be helpful.
The crash can be reproduced every time.
PS.
For some reason Kde crash reporter said Kmix version is 4.3 thus declined to
send bugreport.
