The way I reproduced it is slightly different from OP: Repeat high speed clicking on a program icon with multiple windows until crash occurs. Crash is not total and windows are still usable but the launcher status looks crippled.
Launching `unity &` in a terminal fixes it, and it comes up with a crash reporter saying that the crash report is corrupt and cannot be processed.
Still present in, or regressed to, version 7.4.0
