Hello Massimo, unfortunately like the reporters before you use the wrong bug report for your issue. Daniel startet this report due the noisy output on the terminal about a the pixman_region32_reset() function. Please don't mixup various problems in one report. That makes it impossible to track the issues for us.

We need all threads in the log. Please read the section on the Debian wiki with teh relevant information about making gdb logs. https://wiki.debian.org/Icedove#Starting_Debugging And please append your log as an attachement (so it's not line wrapped) to a suitable bug report. Regards Carsten
