I figured it was difficult to reproduce. I would experience the bug
about once a week in normal usage, I suspect it may have been more
common for me as I usually have gedit open and copy/paste work notes
into it, so my desktop would often be in a state where gedit would
have an unsaved document when I logged out, which would lead to the
failure and 60s timeout. Once the reason was known, the bug could be
reproduced almost every time with gedit running and an unsaved
document. I have also reproduced it by patching mousepad with the
patch that Dimitar Zhekov posted to bug #5379. I have tested both
normal and a cancelled logout with two interacts and both appear to
work with the user being presented both interactions.

Okay, I understand this line of reasoning.
