wikitex bug?

[John Wiedenhoeft]

hi there, 

I'm experiencing problems with lilypond working with wikitex (or the
other way round ;-) )

it seems --no-pdf and --no-ps aren't available anymore, so I deleted
this from wikitex.php, but I get the following:

WikiTeX: lilypond reported a failure, namely:
        terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_S_construct NULL not valid

what does that mean? is this a bug?

tried lily 2.8 and 2.9.

cheers,
john
