'' causes a backtrack

[Daniel Janus]

Enter '' (that's single quote, single quote, enter) in bash. The following output is produced.

nathell@localhost:~$ ''
Traceback (most recent call last):
  File "/usr/bin/command-not-found", line 22, in ?
    if not CommandNotFound(options.data_dir).advise(args[0]):
  File "/usr/lib/python2.4/site-packages/CommandNotFound/CommandNotFound.py", line 119, in advise
    suggestions = self.getSuggestions(command)
  File "/usr/lib/python2.4/site-packages/CommandNotFound/CommandNotFound.py", line 104, in getSuggestions
    result.extend(db.lookup(command))
  File "/usr/lib/python2.4/site-packages/CommandNotFound/CommandNotFound.py", line 87, in lookup
    return [ Suggestion(row[self.TEXT], magicSplit(row[self.PROGRAMS], ",")) for row in self.db.lookup(self.COMMAND, command) ]
IndexError: list index out of range
-bash: : command not found

The last line is correct, but the backtrack should not be visible.

Occurs both in trunk and version from Edgy.

Indeed occurs on edgy. Fixed in feisty.

[Zygmunt Krynicki (zyga)]

Fixed in trunk while removing support for suggestions.
Suggestions will return as a feature one day.

[Zygmunt Krynicki (zyga)]

As consulted with mvo, olny high priority or critical bugs are fixed in -updates.
