Bug 191093

bash is the program which provides the tab completion - not Konsole.  Can you try running Konsole with the --noclose argument and see whether Konsole still quits unexpectedly?

with --noclose now I get this dump, but can't tell if it's a bash or konsole problem:

Hi Raffaele,

I marked this report as UNMAINTAINED because we do not provide updates for KDE 3 any more.  I might be able to help find out where the problem is but if it turns out to be a problem with Konsole, which I think is unlikely given that is is bash that is crashing, we won't be able to 'fix' it.
