Description of problem:
Liveusb-creator crashes with the "Unknown dbus exception:" displayed in the gui and the following output to the terminal window it was started in.

$ liveusb-creator --reset-mbr

Version-Release number of selected component (if applicable):

liveusb-creator.noarch                  3.11.1-1.fc15                   @updates


How reproducible:
always

Steps to Reproduce:
1. run: liveusb-creator --reset-mbr
2. select the iso
3. click the "Create Live USB" button
  
Actual results:
crashes and wedges with the above msg. 

Expected results:
no crash or wedging

Additional info:
The --reset-mbr doesn't seem to effect the results.  It crashes either way.

Comment 1 Luke Macken 2011-06-21 16:57:23 UTC
I made a minor tweak to the exception handling in this case. It most likely won't fix the issue, but it should hopefully make the "unknown" dbus exception more obvious.

Please try and reproduce this issue with this update, which is on it's way to updates-testing:

Thanks!

Comment 2 Tomas Miljenović (TomasM) 2011-07-21 12:02:21 UTC
That build (3.11.4-1) made the problem disappear for me.

Can I help with any more feedback, or should this bug be closed?

Comment 4 Fedora End Of Life 2012-08-07 20:20:49 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
