Bug in equation label

[Anand Rangarajan]

Sorry if this has come up previously but I've encountered a problem with 
lyx equation labels (lyx-1.6.7 on linux x86_64). When I use the label 
'x=1' for an equation, lyx changes it to 'x=00003D1'. If I edit and save 
the lyx file in emacs, then the next time lyx opens the file, the label 
appears as 'x=1'. However, after editing and writing the file in lyx, 
the label reverts back to 'x=00003D1'.

I have not tested lyx-2.0 <alpha> to see if the bug appears there as well.
