Version: unspecified (using KDE 4.7.0) OS: Linux Hi, I've placed on my desktop an instance of folder view widget pointing to a samba share (eg: smb://mynetworkgroup). Everything looks fine (as you can see in the attached screenshot) but when I restart my computer, while plasma-desktop is loading, I systematically get a crash of the entire plasma-desktop. The problem happens only during the log-in. If I remove the widget or change the view to a local folder, the problem does not shows anymore. Thank you for any support. Reproducible: Always Steps to Reproduce: 1. Place on your desktop an instance of folder view widget pointing to a samba share (like smb://yourworkgroup) 2. Restart the system 3. During log-in you'll get plasma-deskop crash Actual Results: plasma-desktop crashes. Sometimes a KDE windows appears notifying the crash. Sometimes I got an entire black screen and I have to manually re-launch plasma-desktop from shell Expected Results: Plasma desktop should not crash

First, is still problem still relevant in more recent versions of KDE, v4.9 or higher ? If so, the backtrace you provided is missing line #. Please install the debug packages for kdelibs, reproduce the crash and post the resulting backtrace here.
Absolutely. Crash still occurs with newer versions of KDE. Here is the backtrace with line # you requested.
