Description rdnetto 2013-11-18 12:34:20 UTC

When there are multiple tabs (conversations) open in a single window, vertical scrolling (using the mouse's scroll wheel) rotates between them. However, if the user (accidentally) scrolls horizontally, the window closes.

Reproducible: Always

Steps to Reproduce:
1. Open multiple conversations.
2. Place cursor over tab
3. Scroll horizontally (requires a mouse with horizontal scrolling support)
Actual Results:  
Window closes. The telepathy presence widget that runs in the background is unaffected.

Expected Results:  
Rotated between tabs, as if vertical scrolling had taken place.

Do you know if this happens on any other KDE/Qt application as well?

Also, to know better what's going on, we'll need a backtrace from you. You can do that by running

gdb --args /usr/lib/kde4/libexec/ktp-text-ui --persist

(paths may be different) then gdb loads, type 'run', empty window should appear, then just open two chats and do the scroll. gdb should say the program crashed, so type 'bt' and you'll get a backtrace. Then please paste the backtrace here.

Thank you.

Output from GDB (incl backtrace)

This bug does affect other KDE programs - I was able to reproduce it in Dolphin's preferences window under the view modes section.
The QtCore library is from package dev-qt/qtcore-4.8.5

Additional info: it only happens when you scroll on the blank area next to the tabs, not on the tabs themselves.

The backtrace seems to go on indefinitely, so I only included the first page of output.

Cool, that means the problem is not in our code, but rather more "upstream".

Reassigning to kdelibs.
