I used the updater to switch branches from Beta to Stable. (126.96.36.199 to 188.8.131.52)
When MD went to re-open, a second dock icon appears.
The second dock icon, once closed, does not re-appear (you can use the old icon, the one locked to the dock, as normal to open and control MD)
This hasn't seemed to have any effect beyond the aesthetics, so marking it as trivial.
^SS of double dock icon.
This has slightly more annoying behavior than I had previously reported.
When this happens, I have to force quit the second instance.
Bumping from trivial to minor.
Is there any way to reproduce this on demand? Perhaps the old MD hung on exit, so both the old and new ones are running. Could you get a stacktrace from the hung MD?
I will try to make this happen reliably and get the stacktrace. I saw this behavior today once only on Snow Leopard and not at all on Lion during my updater testing, so it's intermittent.
Sorry for not grabbing the trace when I filed, should have done that. I imagine I was deep down another rabbit hole and felt the need to record the behavior at least.
I just saw this issue again upgrading from:
to the current alpha channel
After 'kill -QUIT', the log in console was useless.
Gonzalo showed me how to use GDB to get the stacktrace:
Hope this helps!
Looks like the iPhone USB debugger connection's CFRunLoop.
This happens if you're debugging an iOS app on device, the app crashes and then try to update.
Fixed in 154ab8587fb (md-addins master).
