Hi,

this bug is very similar to bug #2927.  I could not reopen it, so here is a new one.

This bug occurs in a reproducible way when I do this:

 - I type an "apt-get install SOME_PACKAGE" command, then "Enter"
 - While apt-get starts up, I select the command with the left mouse button (in order to paste it to another konsole where there is an SSH connection to a remote system)
 - If I'm not fast enough, apt-listchanges starts a "less" pager to display packages changelogs.  The text that I selected is therefore not displayed any longer and replaced by the changelogs display by "less".
 - Konsole crashes.

This happens every time I do this.  This happens on my i686 system and onn my amd64 system.

Here is a backtrace:
