Bug#642405: debian-installer-launcher: Synaptic GUI prompts for root password, then closes. Konsole error says, 'kexec' is not a valid plugin.

[AS <jimmyjarmush@yahoo.com>]

Package: debian-installer-launcher
Version: 5
Severity: normal


Fresh install, updated (from konsole), Synaptic GUI wont run.
Tried to invoke debian-installer-launcher from konsole, but:

ERROR: 'kexec' is not a valid plugin. Check and try again.

Significance of last sentence is unfortunately not clear to me.
If it were, I d probably not file a bug.

Tnx AS
