* I get "Trace/breakpoint trap" error when I first click "Help/PostgreSQL 
Help" and then perform fast clicks on help page :)

     

Known, very unfortunate thing, and yet another non-SSL related bug.
On my machine, this isn't traceable, because my desktop freezes when I 
encounter the problem while running under debugger's control (already 
upgradest to latest gdb).

   

Just a suggestion, I was able to generate a bt for this by launching gdb in a standalone text console (ctrl-alt-f1) with export DISPLAY to my Xserver and then came back to X with the shortcut you all know(ctrl-alt-f7 for display 0)... By doing this, the desktop freezes but gdb is still usable in the text console... may be you could try to trace this way although this is not a real confortable situation...
 

Good suggestion!

I was able to locate the problem. I couldn't fix it ultimately, but the 
attached patch, which should be added to our snapshot, is a workaround 
(posted to wx patches as 854137). For unkown reasons, while selecting an 
invalid color is returned, and setting that invalid color will result in 
a wxASSERT. Unfortunately, this happens while rendering, ultimately 
freezing the desktop while debugging.

Eeh Aaaah!
