Hi Nicolas,
indeed, my code was bogus, trying to remove non existing channel, though I
still think it should not cause Ape to crash. However, I managed to
reconstruct the whole crash scenario:
1. on "left" event I also remove the channel, sth like this:
Ape.addEvent('left', function(iUser, gameChannel) {
....
Ape.rmChan(gameChannel);
}
2. Somewhere else in the code I called Ape.rmChan(gameChannel), though there
were still active users on the channel. In that case, the "left" event was
called first and removed the gameChannel. After that, the
Ape.rmChan(gameChannel) tried to remove the gameChannel again and it Ape
crashed.
I will obviously have to do something with my code, but I hope you will find
this information helpful as well.
Best,
Matija
