Tests may fail (with older PICA::Data?)

On some of my smokers t/04-exporter.t fails:

#   Failed test at t/04-exporter.t line 86.
#          got: '<?xml version="1.0" encoding="UTF-8"?>

t/04-exporter.t ........ 
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/4 subtests 

Statistical analysis suggests that it passes only with PICA::Data 0.34 --- so probably the minimum prerequisite version should be adjusted.
