-- Information about the crash:
My PC returned from sleep and KWin crashed.

I'm sorry for a possible duplicate, the new Konqi tool unfortunately makes it impossible to compare backtraces unless you memorise it beforehand.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>}
