Depending on your explorer preferences, a crash of the explorer
crashes all explorer windows, which alone is ugly.
More serious, windows sometimes, but not always can recover
and automatically starts the explorer again.
Admitted, I didn't have this hehaviour caused by tsvn yet
(at least as far as I know - currently I have overlways disabled
anyway because it often causes the explorer hang for several seconds),
but I have quite often that the explorer crashes in that way.
And thats REALLY ugly.
Because of this I think crashing shell extensions are a major issue.
