Remote, embedded debugging

[Timo]

Dear List,

This is my first post on this list. I'm working for a small company in 
Finland on mostly ARM-based embedded systems. I've been using KDevelop 
as an IDE and debugging frontend from ancient times and I'm quite used 
to it.

But there is a couple of quirks I would like to talk about.

When I start debugging session, KDevelop reports about an error:

<<<<
The debugger component encountered internal error while processing reply 
from gdb. Please submit a bug report.

The exception is: MI type error
The MI response is: ^done
 >>>>

However, debugging works after that, mostly. I'll paste 'internal 
commands' output later.

KDevelop seems not to tell GDB about the executable file to be debugged. 
I have put it into the gdbinit file as a 'file' command but I think 
KDevelop should take it from the 'Executable' field in the 'Launch 
Configuration'. At least older versions did.

My breakpoints doesn't activate. I have to delete them altogether and 
then set them again. In older versions of KDevelop it was enough to 
disable and enable them during the session.

Am I doing something wrong, should I report these as bugs or wait for an 
update?

KDevelop version:

Version 4.0.0 (using KDevPlatform 1.0.0)
Using KDE Development Platform 4.4.5 (KDE 4.4.5)

On Ubuntu 10.04.2
