This does not seem like a problem with KFTPgrabber itself, since no KFTPgrabber classes are mentioned in the backtrace. This bug can therefore only stay open only if it is reproducable - please give steps to reproduce.

Well, in fact im not sure if it happened after I clicked the quick connect button of the right browser or when i tried to connect. I should have read the log more before reporting as it's maybe a bug somewhere in kde. If I can reproduce it again, I will post here. Thanks.

I have removed some code that was obsolete anyway and could have been responsible for this bug. Therefore I am closing this bug report as fixed - if the same problem still ocurrs with the latest SVN revision please reopen it.

Just crashed again when clicking the ok button on the quick connect dialog. The trace is a little different... here it is :

I hope it's not a bug in kde 3.5.5 :(. Anyway, it seems to crash only 1/5 of the time when i try to quick connect... it's not that bad.

I see nothing here that I could fix and I can't reproduce the bug.

Regarding comment #5 - I have tried to use quick connect 10 consecutive times and got no crash. Also the backtrace seems quite wierd since the crash originates somewhere in the DCOP library. Unfortunately I don't know what I could do about it.

*** Bug 143858 has been marked as a duplicate of this bug. ***

Can this still be reproduced using the latest SVN revision (http://www.kftp.org/misc/svn) ?

I just reproduced it with svn. I can reproduce it *almost* everytime by quick connecting and then wait a while to get disconnected from the ftp. Then I just try to connect with quick connect again and it crashes. I can show you another crash log because I don't have what's needed to produce the log.

I just did the following as you said (10 times in a row):
- connected to an ftp site (plain FTP protocol, passive connection)
- waited 60 seconds so the session timed out and I was disconnected
- reconnected to the ftp site
(note that I did not transfer any files since that action was not mentioned in comment #9, I only did the exact steps written above and nothing more)

I was not able to reproduce the crash. Please provide a full backtrace (and please attach it to the report, don't paste it into a comment) and steps to reproduce (in case I should do something not stated at the above description of my attempt). It might be helpful if you specify additional server parameters (connection type, transfer mode, etc).

I couldn't reproduce the crash since my last message, so I mask as resolved... thanks for your work =).
