Crash/Freeze without Internet #440
Description
Reported by ambossarm on 07 May 2009 22:57:37 UTC
If I have no Internet Connection and KVIrc runs it goes black ("dead").
If I run it without gdb I have to kill it after that. If I run it within gdb attached after KVIrc started and I enter "quit" in gdb the KVIrc window comes back to live.
On the "Server Status Window" I see only a single try to reconnect if the window goes black, so it happens "fast"
I disconnected my Internet Connection at 0:20 and the first (and only) reconnect try was at 0:41
Backtrace:
Program received signal SIGPIPE, Broken pipe.
