[E-devel] Segfault when enabling ibox

[Mike R. <mi...@re...>]

After compiling the latest e about an hour ago (using the new 
thinktux.net server), I was unable to load any other theme than the 
default theme. When I re-ran the build script, it reported changes in 
eet and then I was again able to load another theme. However, I get a 
segfault (two actually) when trying to enable iBox. I attached a gdb 
from a virtual terminal and have the backtrace attached (my comments are 
in CAPITALS):

Random quote of the last-time-I-ran-bash:
'Twas midnight, and the UNIX hacks
Did gyre and gimble in their cave
All mimsy was the CS-VAX
And Cory raths outgrabe.

"Beware the software rot, my son!
The faults that bite, the jobs that thrash!
Beware the broken pipe, and shun
The frumious system crash!"
