Hi,

That's a really weird problem. Is this a clean installation of Fiddler? Also, how did you install Mono on this machine?

Could you try the latest version we released today? It should produce more detailed error log.

I am thinking something is wrong with your Mono installation. Do you run other Mono apps but Fiddler?

I have tried the new version with no luck. The same error, the same stack trace.

Then I installed mono-complete package, tried again, still all the same.

I do not run other mono apps. But on my other laptop, Fiddler Linux works.

It is weird that you get the same stack trace. Fiddler.exe.mdb is present, right? There should be line numbers in the stack trace now.

Almost the same, there are some weird characters. There is Fiddler.exe.mdb, but line number are 0.

I have run mono again with  `mono --trace Fiddler.exe > /tmp/mono-trace`, the resulting tracing file is uploaded to a site found by a Google search (compressed): http://www.filedropper.com/mono-trace

The string "System.Windows.Forms.ScrollBar:set_SmallChange" first appears on line 2036871, hope this will help.

That's actually a different one now which makes it even more weird. Could you, please, try starting it with mono --debug Fiddler.exe ? Sorry for not mentioning this earlier.

Yeah, now there are line numbers. The line "Could not set X locale modifiers" appears sometimes.

This looks more and more like a problem with Mono installation. Could you, please, try reinstalling Mono? Also if it is an option try installing Fiddler on a different Ubuntu machine.
