Hi,
I finally managed to reproduce this bug and fixed it in svn. The issue
occurred (only) on machines which are slow enough for GWorkspace
needing more than 5 seconds to finish launching. The cause of the bug
is a subtle error in r29864, where NSRunAlertPanel returns
NSAlertFirstButtonReturn instead of NSAlertDefaultReturn when it is
run from a non-gui application. This was causing a SIGTERM signal
being sent to GWorkspace and a second instance of GWorkspace being
started.
Note that (thanks to some inexplicable wisdom of Apple)
NSAlertFirstButtonReturn is not equal to NSAlertDefaultReturn and that
the NSAlertXXXButtonReturn constants are meant to be used only with
the NSAlert methods, but not with the old OpenStep dialog functions
(and also not with NSAlert's alertWithMessageText:... class method).
This indeed fixes the problem for me, I did a couple of tests. Very well!
Riccardo
