Yasnippet and AucTex

[Andrzej Pronobis]

Hi,

I'm using yasnippet with autocomplete in auctex and it would work great if not for one detail. Whenever I create a snippet which has optional arguments, e.g. \parbox which expands to:

\parbox[Height][item-2]{Width}{}

deleting the argument (e.g. [Height]) with Ctrl+D results in:

yas--field-probably-deleted-p: Wrong type argument: numberp, nil

Is there any way this could be fixed or debugged?

Thanks,

Andrzej
