flyback refuses to start

[GoogleCodeExporter]

What steps will reproduce the problem?
1. launch flyback successfully
2. make a snapshot
3. close flyback when done
4. modify some files
5. open flyback
6. make another snapshot
7. close flyback
8. attempt to open flyback
9. fail

What is the expected output? What do you see instead?
I expected the program to launch and give console output. Instead, there 
is no console output nor any GUI

What version of the product are you using? On what operating system?
Version 0.3 on a fresh install of Kubuntu 7.10 on x86.

That should be version 0.3.3. Sorry for any confusion.

it doesn't put out a stack trace?
does it exit, or run indefinitely?
is it chewing through cpu or io cycles?

how would I find the stack trace if it were to make one?

The program exits after about 1 second of real time (according to top) without 
using any noticeable amount of CPU time, nor I/O cycles.

I'm running this as root, so I think my problem may be connected with Issue No. 
21.

Although the patch given in Issue No. 21 now makes the program give output in 
my 
case, it doesn't help much since the program still refuses to start in the way 
it's 
intended, regardless of the account I use.

The new output is "error importing gtk: quiting :-(".

well, it's a gui program.  i assume you're logging in as a regular user, and "su
-"ing to root?  no graphical program will run that way.

but you should be about to run it as "sudo python flyback.py".

I've been sudo-ing, and `sudo bash`-ing, and running it as a regular user, and 
still everything returns zero output (unless I apply the aforementioned patch), 
with no gui, no noticeable CPU usage, and no noticeable I/O usage. I have all 
the 
file privileges to everything in the flyback directory, and I've installed all 
of 
the dependencies as specified.

do you have "python-gtk2" and "python-gobject" installed?

Original comment by pub...@kered.org on 13 Nov 2007 at 12:36

[GoogleCodeExporter]

Yep.

I'm not too attached to this install of Kubuntu, perhaps I should try with a 
100% 
out-of-the-box configuration and package set? After all, it ran flawlessly the 
first two times I tried.

I've reinstalled Kubuntu, Reinstalled Flyback and it's dependencies, and 
everything
seems to be working... Although I haven't installed skype, sshd, or any of the 
things
I had on the old install yet.
