I've verified this bug under a fresh install of Natty. It appears to be a library mapping.
If you run tomboy with debug flag (by setting TOMBOY_TRACE), you see that DllNotFoundException is thrown when you try to open help: ayan@sierra:~$ export TOMBOY_TRACE=true ayan@sierra:~$ tomboy ** Running Mono with --debug --trace=true ** [0x7f9c3e8e8760:] EXCEPTION handling: ArgumentException [0x7f9c3e8e8760:] EXCEPTION handling: ArgumentException [0x7f9c3e8e8760:] EXCEPTION handling: GException [INFO 04:39:53.669] Initializing Mono.Addins [0x7f9c3e8e8760:] EXCEPTION handling: DllNotFoundException strace shows that this happens after trying to open libglib-2.0.dll.la: open("libglib-2.0.dll.la", O_RDONLY) = -1 ENOENT (No such file or directory) write(1, "[0x7f9aa0ffe760:] EXCEPTION handling: DllNotFoundException\n", 59) = 59 I think mono tries to resolve this by looking for libglib-2.0.so which is in the ldconfig cache: ayan@sierra:~$ ldconfig -p | grep libglib-2.0 libglib-2.0.so.0 (libc6,x86-64) => /lib/x86_64-linux-gnu/libglib-2.0.so.0 libglib-2.0.so.0 (libc6) => /lib32/libglib-2.0.so.0 libglib-2.0.so (libc6) => /lib32/libglib-2.0.so So it should work! http://www.mono-project.com/DllNotFoundException has good debugging information. I'll continue to debug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/667736 Title: help content not available To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/667736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
