Hi Carsten, I'm sorry to say that the crash isn't reproducable anymore since the mail provider is working again (i.e. riseup's smtp server sending mails). This hints for icedove having problems with error handling.
If the problem reoccurs, I will try to collect the full log and will use the iedove-dbg package. Btw. I'm using the current icedove version in testing. i.e.: apt-cache policy icedove icedove: Installiert: 1:45.4.0-1 Installationskandidat: 1:45.4.0-1 Versionstabelle: *** 1:45.4.0-1 900 900 http://ftp.at.debian.org/debian stretch/main amd64 Packages 100 /var/lib/dpkg/status Regards, Stefan On 2016-11-04 08:47, Carsten Schoenert wrote: > Hello Stefan, > > On Thu, Nov 03, 2016 at 11:18:32PM +0100, stefan esterer wrote: >> the attachement contains the backtrace collected via (gdb) thread apply >> all bt > > please add the *full* log created as described in > https://wiki.debian.org/Icedove#Starting_Debugging > > We don't know which version you using nor were the segfault is happen. > We "only" have now the backtrace.
