EDM x-y plot crash

[<Euan.Troup@csiro.au>]

Hi,

I am having a problem with the EDM x-y plot widget causing the main edm program to crash. The crash can occur when updating the widget or when switching between edit mode and execute mode in edm. The crash looks like:
 edm -m "prefix=askap:test:,antid=ask01:,shelf=s4:,board=b1:" xy1.edl 
*** glibc detected *** double free or corruption (!prev): 0x00000000006d7940 ***
Aborted

This crash has occurred on both Linux and MacOS Snow Leopard. Both systems are running in 64-bit mode. The edm versions tested are edm-1-12-21 and edm-1-12-33. Any suggestions for a workaround would be gratefully accepted. 

cheers,

Euan.
