I'm on Debian testing (Stretch). When using icedove, forwarding certain emails causes X to crash as soon as I press "Send".
The console that shows up after X has crashed shows a helpful (?) message: "glamor_picture.c:291: glamor_upload_picture_to_texture: Assertion `!pixmap_priv->fbo' failed. xinit: connection to x server lost". I figured out that glamor_picture.c is part of the xorg package.
Here are my package versions:
I already tried downgrading icedove to the version in Jessie, but same problem occurs. I tried Thunderbird from Sid, same problem.
It seems that the problem is in xorg, and has already been fixed upstream (see https://bugs.freedesktop.org/show_bug.cgi?id=99346). I checked to see whether Sid had a newer version of the xorg package and, alas, it does not.
Anything I should do to help make sure this problem does not make it into Stretch when it is released as stable? I'm a relative newbie to Debian.
Unfortunately, I forward messages a lot, so I need a work-around until this is fixed. Any ideas?
