Hi guys!

I'm getting the following error message when I search the catalog:
"Can't call method "data" on an undefined value at
/usr/share/koha/lib/C4/Search.pm line 1915.
For help, please send mail to the webmaster ([no address given]), giving
this error message and the time and date of the error."

Has anyone ever experienced this?
Thanks!
