Package: konqueror
Version: 4:4.11.5-2
Severity: normal
Forwarded: https://bugs.kde.org/show_bug.cgi?id=333432
Application: konqueror (4.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.6
Operating System: Linux 3.13-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)
-- Information about the crash:
- What I was doing when the application crashed:
Pressing the Ctrl key shows keyboard shortcuts for all links on the page. In a
dynamic menu, hovering over the top level menu items reveals a submenu with
more links (e.g. https://www.teckids.org), and clicking the link leads to a
submenu page. Now doing the following leads to a situation where invalid links
are referenced:
1. Press Ctrl to activate keyboard navigation
2. Press the key for a toplevel menu item that has a submenu
3. After the submenu opens and before the next page loads, press Ctrl again
4. Wait for the next page to load
The keyboard shortcuts for the submenu items will remain active, pressing one
of the keys denoted by them will reference an invisible link (the submenu is
not active on the newly loaded page) and crash Konqueror.
-- Backtrace:
