Bug 816381

when launching s-c-lvm it shows the "reloading lvm" message dialog, updates the right pane and then crashes immediately.
there are two problems:
ZeroDivisionError: float division by zero and pixmap == None in cylinder_items.py
detailed output is on the bottom.

if i replace "model.foreach(self.check_tree_items, [vgs[0].get_name()])" with pass in Volume_Tab_View's init the ZeroDivisionError vanishes and s-c-lvm starts up. i can then actually browse all the "logical view" items as well as "uninitialized entities", but clicking on "physical view" or its child makes it crash with the second error.

i am using latest git (bb1d953d86e3fcb9826e67f49a7d227c3976f29b) on ubuntu 12.04 and ubuntu's 1.1.15-1ubuntu1.
i am executing directly in the source tree because i could not get it to "build" on time.
sorry if this is the wrong (ie. !upstream) tracker. it was impossible to find out the right one :(

How reproducible:
that's the question.

The program 'system-config-lvm.py' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 6048 error_code 11 request_code 53 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

the whole thing is on top of a LUKS device, but i have an almost identical setup that is fine... here is the same output of the WORKING setup:

bug #590917 looks identically but the description is a bit different. maybe due to changes between then and now...
if you need more information or have some things to test, i wont run away soon.
