Hello.

I'm seeing a pcbnew hang at 100% cpu, but only if I run it via the kicad
window. If I start pcbnew from a console window it runs fine. This is with
a few day old kicad-testing branch, Kubuntu 13.04 64bit.


Here is the stack trace:

I put a breakpoint on the line after the call to wxDir::GetAllFiles() in
EDA_APP::OnInit() and it doesn't look like the GetAllFiles() call ever
returns.

I don't see any outstanding bugs and the folder being passed into
wxDir::GetAllFiles() seems perfectly fine.

(gdb) frame 88

202                 unsigned cnt = wxDir::GetAllFiles(

(gdb) print i
$2 = 0
(gdb)


Ideas?
