[Mono-dev] Monodevelop doesn't run...

[luca.f at libero.it]

Hi to all,
   I'm new to mono and monodevelop.

I've just installed them on my Ubuntu 7.10 from sources:

mono-1.2.6 & monodevelop-0.18.1

Everything seemed to be ok, but when I try to run monodevelop, it fails with this message:

"MonoDevelop failed to start. The following error has been reported: The required addin 'MonoDevelop.SourceEditor,0.18.0' is not installed"

Running strace and grepping "SourceEditor" from its output I got these lines:

lstat("/usr/local/lib/monodevelop/AddIns/MonoDevelop.SourceEditor.dll", {st_mode=S_IFREG|0644, st_size=184832, ...}) = 0
stat("/usr/local/lib/monodevelop/AddIns/MonoDevelop.SourceEditor.dll", {st_mode=S_IFREG|0644, st_size=184832, ...}) = 0

Maybe something is wrong with this /home/luca/.config/MonoDevelop/addin-db-001... ? 
Has someone any idea?

Thank'you
Luca
