mono applications don't start anymore

[Manuel Schmid]

Binary package hint: mono

Since approximately 10 days, all mono-application (tested with Tomboy, F-Spot and Desktop Drapes) don't start any more. When I try starting them from the console, no error message is displayed and the hard drive makes a strange clicking noise.
The problem occurs on a Sony Vaio laptop running Ubuntu 7.10 with the latest updates installed. The laptop is not my own, but If more info about the hardware or package versions are needed, I can provide them.

I'm having a similar problem, but I am getting errors. I've tried reinstalling everything having to do with Mono. I think this might be a MONO_PATH issue. Here's the information output when running the various programs.

gtkpod is complaining also. I didn't realize it had mono depends...

/opt/mono-1.2.6? Where did you install Mono from?

It seems like your Mono distribution installed a bunch of .so's that are not compatible with your Ubuntu install.

[flickerfly (josiah-ritchie)]

I found out my problem. It had nothing to do with a bug. Sorry for the noise. Manuel, I had to remove my /opt/mono-1.2.6 directory and reinstall mono from rubenv's repositories to get the latest mono from his stuff. The problem turned out to be a 2 competing installations of libraries. The Cairo guys got me straightened out. I did have to also re-install a couple mono packages to get everything back in its proper place and to let everyone know where they were.

I'm going to mark it as invalid because because I expect Manuel's problem to be similar and my problem clearly wasn't a bug in mono or ubuntu, but with me. Manuel, correct the status if I'm wrong.
