Thanks for the report. Could you please provide a backtrace of the crash? (see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Backtraces )

Sorry it took me a while to figure out how to recompile stuff so the debug output is something sensible. I recompiled kdelibs, dolphin and dolphin-plugins with debug information. Enclosed are the resulting kcrash file, output from command line and output of 'gdb /usr/bin/dolphin'. I hope you find these useful.

Quit anyway? (y or n) y

Thanks a lot for the efforts, but sadly exactly there where it crashes there is no backtrace available... There should not be a need that you recompile everything to get a useful backtrace: All that should be needed is that you install the *dbg-messages for KDE from your distribution. If Dolphin crashes a debug-dialog should pop up showing the crash with the backtrace.... Hm, I just see you're using Gentoo, probably there recompiling is the way to go ;-) But assuming that you have your current environment: Could you probably start Dolphin with gdb again and after it crashes please type 'bt'? We'd need to full backtrace to have any clue whats going on.

Oh crap... the backtrace

reminded me of something I had totally forgotten: I've been using dolphin-box-plugin, which provides Dropbox integration for dolphin ( http://quickgit.kde.org/?p=scratch/trichard/dolphin-box-plugin.git&a=summary ) for quite a long time, and it had worked just fine until now... So, I removed dolphin-box-plugin, and... dolphin started working again. Sigh.

Dropbox - KDE integration is really in a sorry state: kfilebox is buggy as hell, and dolphin-box-plugin, while providing only very minimal features, has so far performed without a hitch, but it seems to be somewhat abadoned project. I suppose I have to give it up for now.

Thanks for the backtrace - yes, it looks like a Dropbox-issue...

New crash information added by DrKonqi

dolphin (2.1) on KDE Platform 4.9.2 using Qt 4.8.2

- What I was doing when the application crashed:

I opened the folder "~/Dokumentai" containing a file named 

"C:\nppdf32Log\debuglog.txt"

The crash happens every time, and if I remove the aforementioned file, the crash dones not happen again.

Git commit 1a1ba8184ddc37e6dd82c81cd954a92c6e55455d by Emmanuel Pescosta.
Committed on 17/02/2014 at 10:58.
Pushed by emmanuelp into branch 'master'.

Added a Dropbox version control plugin for Dolphin.

This Dropbox plugin is based on the work of:
Sergei Stolyarovs - https://bitbucket.org/cancel/dolphin-dropbox-plugin
Thomas Richards - http://trichard-kde.blogspot.co.at/2010/12/introducing-dropbox-integration-for.html

What I have done:
- Ported the old source code to the newer KVersionControlPlugin2 interface
- Use the Dropbox client to form the context menu more dynamically
  (If the Dropbox guys add a new feature to their client, Dolphin can make use of it automatically)
- Fixed a crash (Dolphin-4.8.2 segfaults when a file with special characters is present)
- Replaced the item version changed timer with a file system watcher -> No useless updates and immediate update on changes
- A lot of code/coding style related changes
- Made symlinks work with Dropbox
