errors.ubuntu.com sees this first in 4.2.7 and it is still happening at least through to 4.3.3. Possibly related to upstream https://bugs.freedesktop.org/show_bug.cgi?id=77315, which touches related areas of code.

Interestingly, errors.ubuntu.com does not list a single instance of this happening beyond 4.3.3 even though 4.3.4 and 4.3.5 are already in the ppa for extended amounts of time. Lets see, if this changes if the queued 4.3.4 update to utopic is released.

Likely solved by upstream commit 8bc56801af0540c0496c1f8ddd335578a8791017/I37cbf8ff49c6ccf38bfac3e1c8c6492ac7bad61b in 4.2.8 and 4.3.5 and master.

Status changed to 'Confirmed' because the bug affects multiple users.

If more infos needed, i got a crash today and will save the bug report.

Since there is no know way of reproducing the crash what is the advised way of going up verification for this one? Install the package and then wait? Seems basically impossible to verify to me.

@r0lf well generally it falls back to has anyone been running the -proposed version and found an other regressions?
