(*** This bug was imported into bugs.kde.org ***) Package: konqueror Version: KDE 3.0.5 CVS/CVSup/Snapshot Severity: normal Installed from: Compiled sources Compiler: Not Specified OS: Not Specified OS/Compiler notes: Not Specified I looked for a file containing a string using the find tool in Konqueror opened an html file in the results hit the back button. First I see a "Malformed URL" error in a message box then Konqueror crashes.

--=.iBfA44cbTpKn5A Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Package: konqueror kfind Version: KDE_3_0_2_RELEASE OS: Linux 2.4.18 Hi After a sleepless night I have patch for this bug :) It seems that "emit finished()" causes the crashes. What connects to this signal? I couldn't find anything significant. Backtrace shows that it causes openUrl to be called with some strange parameters. As far as I know commenting it out causes no side effects. Change in libkonq also fixes strange behavior when find tool gets closed if back button is pushed.
