Bug Description

Package: http://edge.launchpad.net/lottanzb/0.5/0.4.95/+download/lottanzb_0.4.95-1_all.deb
Platform: Ubunty Jaunty Jackalope

I upgraded from lottanzb 0.4.1 to 0.4.95, and ran into a problem. Lottanzb wouldn't start up, because the directory /home/<user>/.local/lottanzb/plugins did not exist. Lottanzb hangs, displaying the error (on console startup)

Traceback (most recent call last):
  File "/usr/bin/lottanzb", line 7, in <module>
    app.run()
  File "/var/lib/python-support/python2.6/lottanzb/core.py", line 355, in run
    sys.exit(self.main(sys.argv))
  File "/var/lib/python-support/python2.6/lottanzb/core.py", line 324, in main
    self.launch()
  File "/var/lib/python-support/python2.6/lottanzb/core.py", line 188, in launch
    self.plugin_manager = PluginManager(self, self.config.plugins)
  File "/var/lib/python-support/python2.6/lottanzb/plugins/__init__.py", line 544, in __init__
    self._find_plugins()
  File "/var/lib/python-support/python2.6/lottanzb/plugins/__init__.py", line 550, in _find_plugins
    for name in listdir(path):
OSError: [Errno 2] No such file or directory: '/home/<user>/.local/share/lottanzb/plugins'

Easily worked around by manually creating the plugins directory.

Hi Frank Zwart,

thanks alot for reporting this issue! I just commited a fix, which will be part of the final version of LottaNZB 0.5. In fact, it might even be a good idea to release a second beta version since many users are likely to have this problem.

status:	New → Won't Fix
status:	Won't Fix → Fix Committed
importance:	Undecided → High

In LottaNZB 5.0 it fails to start. It can't find ~/.local/share/lottanzb. Creating the directories fixes it as well.

Hi Marcel de Vries,

are you sure that this happened with the final version of LottaNZB 0.5 released tonight? I'm quite sure I fixed the bug. If you're really using LottaNZB 0.5 (not 0.4.9x), could you please remove the "lottanzb" directory in ~/.local/share again, run "lottanzb" in a terminal and copy the error messages to this bug report?

Regards,
Severin

According to Synaptic I'm running LottaNZB 0.5-1. If I remove lottanzb from ~/.local/share/ it starts flawless. But if I remove either ~/.local or ~/.local/share it doesn't.

As you can see it does output ~/.local/share/lottanzb and that is what I saw. But it's just ~/.local and ~/.local/share.

If it's important. This is on a fresh jaunty install which probably doesn't contain ~/.local after installation. If not than maybe "cp -ax" dropped empty directories when I change my /home partition.

Thanks for providing me with additional information. I didn't know that the ~/.local/ and ~/.local/share directories don't exist after a fresh installation of Ubuntu. The directory will be created soon after the installation I guess, since there are many programs that write to this directory and even the trash is located there.

Fixing this bug is trivial. Since the crash only happens on a truly fresh installation and can be easily worked around, there's no need for an emergency release I guess. But it should definitely be part of LottaNZB 0.5.1.

I'll file a new bug report. Thanks again for your help.
