The package need to be rebuilt, but the original source package does not work. Need a little bit patch as enclosed.

[Jean-Baptiste Lallement (jibel)]

Thanks for your report and the patch.

This is reproducible in Oneiric up to date. Setting to triaged/high because the application can't start at all.

[Rex Tsai (chihchun)]

the original source deb missed build depends on libsyncdaemon-1.0-dev, enclosed please find an updated patch.

Debdiff doesn't work for me:

Applying patch 02_dllimport.patch

[Maia Everett (linneris)]

Simply rebuilding the current package in oneiric with libsyncdaemon-1.0-dev added to build-depends seems to do the trick.

[Rex Tsai (chihchun)]

Fixed in 1.6.1-0ubuntu5.

This error is still present in Ubuntu Oneiric, but for mono applications created with monodevelop and using Gtk#, but for some reason not for applications bundled with the operating system.

The same happened to me in Windows, and the problem disappeared upgrading to the current version of Mono (2.10.6). I guess this is going to be the same thing.

Unfortunately, recompiling applications is not an option, as Monodevelop 2.6 is unable to find the Gtk# in the system (?). Again, the same happened to me in Windows, and upgrading to the current version (2.8) solved the problem.

Would it be possible to upgrade these packages to their current versions, so this bugs disappear?
If not, how can I solve this in my system, so I'm able to use mono again?

Thanks.

baltasarq, please file another bug with apport for more version and crash inforamtion. Thanks
