Description Dario Andres 2008-11-30 14:10:21 UTC

Version:           KDE 4.1.3 (using KDE 4.1.3)
Compiler:          GCC 4.3.2 
OS:                Linux
Installed from:    Compiled From Sources

This bug was discovered when trying to reproduce Konqueror bug 169442.

Here:
Using KDE 4.1.3, Qt 4.4.3
on ArchLinux x86_64

(Have enabled JS, "Activate debugger" and "Report errors" in Konqueror)

- Open Konqueror
- Go to ifile.it
- Select one file to upload, and press "Upload selected files"
- Click "Send files" in the Konqueror confirmation pop-up window
- The file upload doesn't work (because of bug 169442) (maybe a progressbar appears, but nothing will happen later)
- Click "Cancel Upload"
- Accept the site messagebox complaining about the user cancel the file upload
- A JavaScript error pop-up window appears, click Accept
Konqueror Crash

If you need more information, just ask me.
I'm going to check this bug on KDE4.2svn later

Comment 1 Dario Andres 2008-12-11 23:24:47 UTC

Both bug 169442 and this bug seems to be fixed using:
Qt: 4.4.3
KDE: 4.1.85 (KDE 4.1.85 (KDE 4.2 Beta2))
