Laz 2.1 trunk, or 2.0.1 fixes?
Can you attach a list of all threads, and traces of other threads please?

Hello,
I find that the IDE has become very unstable lately. I didn't install any
new packages, didn't update FPC (still on FPC 3.0.4). Just updated
lazarus
from SVN.
4 out of 5 attempts to close the IDE using the window manager button
fails:
lazarus hangs and I must kill it using
killall -KILL lazarus
from a terminal.
It's very reproducible.
Start lazarus
Open package
Compile package
Switch to form editor of start project
Close (window manager or menu file - exit)
-> hang
I can attach to it using gdb. Here is the stack trace:

Seems a bug in the online package manager. Who said once that threads
are evil ? :)
For now I uninstalled the online package manager, but a fix would be
really appreciated :-)
Michael.
