Version: (using KDE KDE 3.4.0) Installed from: Fedora RPMs Compiler: 3.4.2 OS: Linux If I attempt to select multiple .zip files in a folder (10 .zip files or so), and select the "Extract->Extract Here" konquerer right-click menu option, ark fails to extract the contents of all selected .zip files. Usually, it will only extract the contents of 1-4 of the selected files. If I attempt to click "Extract->Extract Here" again on the same selected files, then ark does actually attempt to extract the contents of all selected .zip files. In the process, ark opens a Please Wait dialog box for each .zip file I attempt to open. Also, an Error Dialog box is opened for each .zip file that was already extracted before. Besides that, ark apparently has another bug, one that hangs Konqueror and other apps because it's stuck in a loop or race condition that pegs the CPU usage. If I attempt to "Extract Here" more than 15 .zip files at a time, ark hangs after attempting to open an individual dialog box for each .zip file. I have usually have to kill X for the system to be released. This bug is reproducible, and has been for versions of ark back to KDE 3.0 and before.
Ark will sometimes crash kicker with a signal 11. Here is the Backtrace of the dump: Using host libthread_db library "/lib/tls/libthread_db.so.1".

> ark hangs after attempting to open an individual dialog box for each .zip file Might be related to the crashes you are getting. KWin sends updates to Kicker's taskbar applet which crashes. Could you try to reproduce the hanging konqueror and look which processes are eating your CPU time? Maybe Ark spawns so many processes that the desktop itself is having a hard time getting some CPU time to interact with the user.
When I reproduce the hang, ark appears to peg the CPU meter. It does attempt to spawn multiple unzip processes, but these are listed as defunt in ps. The unzip processes do not appear to be taking up cpu time. Perhaps ark should only spawn one unzip child at a time to reduce overhead if multiple zip files are selected for extraction.
