[Mono-dev] Debugger crashes while debugging ASP.NET app

[passiday]

Hello Lluis,

> Try running MonoDevelop from a terminal, and see which output you get.
> Also make sure you have the latest MonoDevelop and Mono.

The MonoDevelop and Mono was fetched from depositories, using synaptic, on
13th of January. My colleague installed MonoDevelop on his Kubuntu, and
experiences no problems whatsoever. So, this is something connected with my
system.

Below is the console output. Not too much happens in the console, when the
debugger is crashing. But as there are some errors upon running the
monodevelop, and building and running the app, maybe they are somehow
connected with this crash? Maybe there is some debugger log file, where
there could be more info about what is happening?

* Console output, when stating up the MonoDevelop:

WARNING: Cannot find Mozilla directory containing libgtkembedmoz.so. Some
Addins may not be able to function. Please set MOZILLA_FIVE_HOME to your
Mozilla directory.

* When the debugger hits breakpoint:

OnTargetEvent, type - TargetHitBreakpoint

* In the very rare case when the step over works fine:

OnTargetEvent, type - TargetStopped

* When the step over fails:

OnTargetEvent, type - TargetExited



No extra output, connected with the debugger crash is given. Application
execution is stopped, and the browser receives error (FF says "Unable to
connect. Firefox can't establish a connection to the server at
127.0.0.1:8080.").
