PDF file not supported by GS

We are using:

convert 'documento-1335140.pdf' '%d.png'

and gs throws:

**** Error reading a content stream. The page may be incomplete.

**** File has unbalanced q/Q operators (too many Q's) ****

and hangs.

Easy to reproduce with attached PDF file.

Is there any option to avoid gs to hang at least?

Sure, just set the 'NOBUGS' command line switch.... Oh yes, sorry we haven't
managed to fully implement that yet.

Or don't use buggy PDF files.

Or at the very least try a current version of the software before reporting a
bug. Version 9.16 onwards (so that's any version less than 2 years old) don't
seem to suffer from the problem. Presumably because we've added code to work
around this specific kind of invalid PDF file.

Note that 'convert' is an ImageMagick tool, you should always try to reproduce
Ghostscript bugs using *Ghostscript*, and provide the command line
configuration which reproduces the problem.
