Hi there,
I was surprised to discover (when re-working gengal) that if you do
some drawinglayer operations then it is necessary to shut-down UNO by
disposing some UNO component - before exiting - to avoid some rather
nasty atexit / static cleanup SEGV :-) One of those things is triggered
by importing svgs into galleries using gengal.
I was wondering if there was some cppuhelper etc. place to publicise /
centralise this fact :-) it seems we do it in desktop/ and also now
gengal/. I append a trace of the clean shutdown path and the problematic
one.
Thoughts ?
Michael.
