I recently updated mono to version 2.11.1 (I know, it's marked as "alpha"...).
I use docky under KDE. Since my update of mono, docky crashes immediately after start. Thus I tried to recompile docky (versions 2.1.3 and 2.1.4), but it fails with the following error:
error CS1701: Warning as Error: Assuming assembly reference `Mono.Cairo, Version=220.127.116.11, Culture=neutral, PublicKeyToken=0738eb9f132ed756' matches assembly `Mono.Cairo, Version=18.104.22.168, Culture=neutral, PublicKeyToken=0738eb9f132ed756'. You may need to supply runtime policy

make: Leaving directory `/var/tmp/portage/gnome-extra/docky-2.1.4/work/docky-2.1.4/Docky.Services'
make: *** [all-recursive] Error 1
Sorry for the long delay.
I've removed -warnaserror from MCS_FLAGS. Can you please try to compile and run it again?
Sorry for responding so late. I just compiled the newer version 2.2.0 without any problems. You can close this bug report. Thanks for the support.
