There was an error in the file indeed:

cs.po: Mismatched quotes:

#: ../src/ui/dialog/tracedialog.cpp:757
msgid "Inkscape bitmap tracing\nis based on Potrace,\ncreated by Peter Selinger\n\nhttp://potrace.sourceforge.net"
msgstr msgid "Vektorizace Inkscape\nje založena na Potrace,\nvytvořeném Petrem Selingereme\n\nhttp://potrace.sourceforge.net"
-----
I've fixed it by removing the unnecessary msgid just after the msgstr keyword.
Translation updated in the trunk revision 13535 (now 39% translated).
Thanks for your update!
