**System Information**
Lubuntu 15.04. ati r300
**Blender Version**
2.72b
As indicated in the title. Even mode works but I cannot change the reference edge (marked as yellow in UI). When I start slide edge from a different POV often a different edge is marked as reference, but still it can't be changed even with LEFT/RIGHT ARROW KEY.
**Exact steps for others to reproduce the error**
A cube subdivided twice -> select a loop (doesn't matter how long or where) -> use slide edge and press E.
