Created an attachment (id=17958)
Fix bug in TextOutputDev.cc

Attaching the PDF file would assist with debugging this problem.

From the stack trace I could see one problem. At #2 the string contains only the unicode byte order marker FEFF. At this point in the code the length should be 0, not 1. Patch to fix this is attached.

Without the original PDF file I do not know if this patch will fix this bug.

[Sebastien Bacher (seb128)]

I've asked the example to the submitter but the description suggests that the pdf was being downloaded and the issue was due to the partial copy rather

[Sebastien Bacher (seb128)]

do you get the issue every time on the mentionned example? could you attach it to the bug?

[Albert Astals Cid (aacid)]

I've commited Adrian's patch, not that we can do much more without more info, so i'm closing the bug.

[Pedro Villavicencio (pedro)]

fixed upstream, thanks for reporting.
