[imp] Errors in logs.

[ANANT S ATHAVALE]

Dear List,

Getting following errors in horde logs (I think when viewing Open Office
Files).

Jan 06 2014 12:52:46 WARN: HORDE [imp] PHP ERROR:
XSLTProcessor::transformToXml(): Using default element rule for ODF element
'text:change'. [pid 26905 on line 126 of
"/usr/share/pear/Horde/Mime/Viewer/Ooo.php"]
Jan 06 2014 12:52:46 WARN: HORDE [imp] PHP ERROR:
XSLTProcessor::transformToXml(): measure_conversion.xsl: Find no conversion
for  to 'cm'! [pid 26905 on line 126 of
"/usr/share/pear/Horde/Mime/Viewer/Ooo.php"]

Are these of any concern?  Anything needs to be installed on server to
solve the issue?
