I can confirm this bug. After doing some SVN log analysis, I believe that the code that implements the LIKE feature has been deleted by accident when moving some code to Semantic Maps.
Jeroen, could you please have a look at the issue? The switch in SMW_SQLStore2_Queries.php line 757 did formerly include a case for LIKE which is now gone. As soon as this is fixed, we will backport the fix to SMW 1.5.1. Existing installations will be able to restore the feature by copying the fixed file. As a quick fix, it should be possible to copy the file SMW_SQLStore2_Queries.php from SMW 1.5.0 [1] into the according place of your SMW installation. This may, however, create problems with queries related to Semantic Maps. If any problems occur, the SMW 1.5.1 file can always be used again [2].
