Description Marat Radchenko 2010-04-14 06:05:54 UTC 
According to g_match_info_fetch docs,
"If match_num is a valid sub pattern but it didn't match anything (e.g. sub pattern 1, matching "b" against "(a)?b") then an empty string is returned."

This is true for all sub pattern except those that are _after_ matched string.

Root of problem: http://git.gnome.org/browse/glib/tree/glib/gregex.c#n822

Testcase attached.
