Version: (using KDE KDE 3.4.3) Installed from: Ubuntu Packages OS: Linux Binary packages: Kubuntu 5.10 (Breezy) kdebase-kio-plugins=4:3.4.3-0ubuntu5 Steps to reproduce: 1) Enter the following URL in Konqueror's location bar and press enter: data:text/plain,hello A message box pops up, saying the document contains binary data and saving will result in data loss, or some such). Also, on my machine the 'Progress Dialogue' box appears, with the URL above as one of the items in it. 2) Clear the location bar, and enter the same URL, and press enter. Result: Konqueror crashes. BTW, I discovered this while looking at other bugs in the 'data:' protocol - it only seems to support the base64 encoding correctly, I think. I'll file a separate bug.

Interestingly, bug 95488 is "kio data crashes application (but not Konqueror)".
Can reproduce. So this is not related to bug 95488. Can't fix it now, but will keep it in mind.

I can confirm the crash on 3.5.9. Konqueror 4 (tested from trunk, r806416) doesn't show the error message and doesn't crash :-) I leave this bug opened for 3.5.
It works on KDE 4.3 too.
