#6 0x00007ff8985e0cba in ?? () from /usr/lib/kde4/plugins/styles/libpolyester.so Looks like a problem of the Polyester widget style. However, I can't reproduce the crash using that style. Does the crash happen when using other widget styles ?
You're correct. The crash only happens when using the Polyester style. None of the other styles I have installed causes the crash.
BTW, version of Polyester style installed is 2.0.0-3build1, also from the Ubuntu repos.
Thanks for the quick reply. Please report the problem to the Polyester developers then.
