--- Comment #6 from Bernhard Übelacker <bernhardu at mailbox.org> ---
I received this crash too with current Debian testing.
Below the top of the backtrace without and the full backtrace with debug
symbols installed.
While in my first crash I think I had also a ssh connection open, I could
reproduce the issue
- with installing neofetch
- starting a new konsole
- starting inside neofetch
- right click while neofetch was still running.

Interesting looks the call to `Konsole::ProcessInfo::isValid` with this=0x0.

I assume these bugs are duplicates to this one: 458157 460764

And bug 391447 seems also kind of related, while it was closed with a commit
changing this:
-        if (isForegroundProcessActive()) {
+        if (isForegroundProcessActive() && _foregroundProcessInfo->isValid())
{

Maybe extend this check by following:
-        if (isForegroundProcessActive() && _foregroundProcessInfo->isValid())
{
+        if (isForegroundProcessActive() && _foregroundProcessInfo &&
_foregroundProcessInfo->isValid()) {

Kind regards,
Bernhard
