Hi all!
On an (almost) fresh install of LXDE on Arch Docky crashes whenever the mouse hovers over it.
- up-to-date Arch/LXDE (executed pacman -Syu today)
- xcommgr is running (but it also happens w/o it)
- Docky starts up, shows default icons etc., everything seems fine
- when mouse hovers over area occupied by Docky it crashes instantaneously:
error 3: BadWindow (invalid Window parameter) request 15 minor 0 serial 2079
mono: cairo-scaled-font.c:459: _cairo_scaled_glyph_page_destroy: Assertion `!scaled_font->cache_frozen' failed.

Debug info from gdb:
=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================Did anybody else run into this? Any ideas how to fix it?
(just in case it matters: Arch is running on VBox 4.3.6. So far, I didn't run into any other crashes or problems with DE or WM)
Thanks & Cheers

Greetings!
If you are still on this issue, I suggest you check out your fonts. Had you been fooling with them?
I once rebuilt my entire OS due to this problem a couple of years ago. It popped up again yesterday and I determined to find the issue.
It was my fonts. I use Funtoo (I used to use ArchLinuxArm so I'm registered here) and just prior to the problem I was fooling with the infinality/lcdfilter settings. After chasing my tail all day today I went and changed some font settings and that was it! For me the same issue occurred whenever I tried to add the weather icon, the best thing about Docky.
I had been fooling with the fonts 2 years ago too...
An ominous and unhelpful error message to be sure.
Good luck.
