#122 Crash in PdfParser::parseName()

[Fxrh]

KDE bug: kfilemetadatareader crashes when hovering with the mouse over certain PDF documents. As it is unassigned in the KDE bug tracker and the crash happens in libstreamanalyzer, I added a second bug report here. For the original bug report with backtraces and PDF examples, see https://bugs.kde.org/show_bug.cgi?id=280772
