webui crashes when the -l parameter is used

[guigui357]

Hi,

I've opened a thread in the support forum ​here because I couldn't use webui since my update to jaunty.

It comes out that webui crashes if a log file is specified using the -l parameter.

This seems to be true only with jaunty (I have another machine still running intrepid and configured exactly the same way, with deluge 1.1.7 as well, and it works).

I used strace to try to understand a little bit where things go wrong. Here are extracts from webuiok.log and webuiko.log, showing the moment things go wrong. Hopefully it will help to find what happens.

from this moment on a lot of apport related stuff, and finally exists later

This no longer happens in 1.2
