Reproduced with Inkscape 0.91 r13725 and 0.91+devel r14201 on OS X 10.7.5 - happens on the command line as well as when exporting via GUI (with latex-export enabled).
Attached is the reduced test case with the 'Flowed text' object which triggers the crash: AFAICT it is the last of the four empty flowed text elements in the original document, which - compared to the other three - lacks an empty <flowPara /> element.
The crash does not occur after manually adding the <flowPara /> element.
