Icicle mode and supercite (gnus) - Lisp error on attribution completion

Icicle mode and supercite (gnus) - Lisp error on attribution completion

[Anupam Sengupta]

When using gnus+supercite along with Icicle mode, the icicle-completion seems to
interact badly with the attribution completion prompt from SuperCite and
generates the lisp error:

(wrong-type-argument listp 0)

The error does not appear at all if icicle-mode is turned off, and all
citation/follow-up in Gnus works correctly as expected.

The issue /may/ be with the mini-buffer completion feature of Icicle, whose
interaction with the SuperCite prompt for Attribution completion does not work
too well.

------ DEBUG-TRACE FOLLOWS -----

After (setq debug-on-error t) and trying a followup in Gnus (for any message), I
got the following backtrace: 

Debugger entered--Lisp error: (wrong-type-argument listp 0)

Thanks for the bug report - it was an Icicles bug. Should be fixed now.

Thx - Drew
