 {{{
 Hi,
 thank you very much for your feedback and the workaround, i'll use it to
 solve my needs.

 I have one question : what's the next step ?
 As i wrote in this ticket, i also sent this bug to poppler support : this
 problem has to be solved by poppler team or by Macports team ?

 Let me know if i can help in any way.

 Thanks again for your help.

 Best regards.

 Guillaume

 As suggested in the poppler bug report that you filed, further debugging
 is required to understand the precise failure mode before it can be
 understood how to fix it and who should do it.

 From the preliminary debugging cited above, it appears that either Poppler
 is sending bad information to cairo_stroke() or cairo_stroke() itself is
 failing on legitimate input.

 Next step is to examine the cairo context passed to cairo_stoke() at the
 time of the error and see how that is causing the memory access error.
 Once this is understood the results can be forwarded to the appropriate
 developers for action.

 If you or anyone else can demonstrate the problem with a simpler pdf file,
 please let me know as that would help a lot.

 Glad that you are able to make progress at any rate.  I'll leave this
 ticket open for now to remind that the issue exists and will try to look
 at it further when time permits.
