[jitsi-dev] jitsi crash, low microphone volume level (debian testing)

Hi Devs,
used now Jitsi latest nightly on Debian Testing 64bit (Lenovo Thinkpad

during call: my partner almost could not hear me (mic level was set to
maximum) - how to solve this?
I have selected Pulse Audio in the menu

Jitsi crashed two times after pressing the video button

(other partner on ubuntu 12.04 32bit, no crash there)

sent the logs to support@bluejimp.com
