KeePass / Mono under Yosemite does not work

macos mono

I installed KeePass as described here but it KeePass does not start - Activity Monitor tells me that Mono is not responding. I have never used KeePass before (if this is relevant).

I am using Yosemite

I am not sure if this a Mono or a KeePass issue, but I also tried Mono 3.10 version and the same happened.

Any experiences with KeePass / Mono under Yosemite or ideas how I could troubleshoot what is happening?

I know about KeePassX - but the consensus seems to be that KeePass is the better option?

EDIT:

I just ran keeps from the command line, and got the following output (no idea what it means...):

Solution 1:

The problem can be solved by installing a new version of mono which fixes this issue, as explained here:

Try installing this mono 3.10 version and forcing a rebuild of your application.

https://www.dropbox.com/s/wrjnv7p8zj1rh5u/MonoFramework-MDK-3.10.0.26.macos10.xamarin.x86.pkg?dl=0

One of the developers on the mono team worked hard to track down and fix this issue. Hopefully, this should be the end of the GDI issues for Xamarin.Mac users.
