The Jabref file field can contain escaped colons, when they are part of
the file description or file name. For example the following bibtex entry
@Article{ES2014,
Title = {An $L^p$ Theory for Stationary Radiative Transfer},
Author = {Herbert Egger and Matthias Schlottbom},
Journal = {Applicable Analysis},
Year = {2014},
Month = apr,
Number = {6},
Pages = {1283--1296},
Volume = {93},
Doi = {10.1080/00036811.2013.826798},
File = {arXiv\:1304.6504v2:ES2014preprint.pdf:PDF}
}
is parsed by Jabref as being linked to a file ES2014preprint.pdf with
description arXiv:1304.6504v2. Currently the bibtex parser of xapers
chokes on this field as it uses split(':') which does not care about the
escaped \:. The attached patch replaces the split with an re.split with
negative lookbehind assertion to correctly handle escaped colons.
Cheers,
Felix
