can confirm this bug. I had multiple kde apps crashes after libpulse0 upgrade from experimental.
I've tried to launch app from terminal ang got symbol lookup error: : undefined symbol: main After downgrade libpulse0 to 4.0-6~bpo7+1 (to latest stable, maybe 5.0.6 will work too) all apps are working correct. -- Best regards, Valery Mamonov.
