Please attach the file to the bug report

Comment 2 Roman 2010-10-19 13:03:39 UTC

Unfortunately file size is bigger then 1000K so I uploaded it to file sharing service. The link http://depositfiles.com/files/t2bukrunw .

Thanks!

Comment 3 Pino Toscano 2010-10-19 21:37:36 UTC

Thanks for the document, good case indeed.
Looks like it is a similar case of the fix I recently did (in the development version) to support the links to named pages whose names are only numbers, but for the TOC items.
