From my limited Googling, I believe this is a Linux-platform-only thing, though I have been unable to reproduce it because of a problem installing ISOLDE in the current daily build (#2161)

[pett]

I could not reproduce this using the generic Linux daily build on host 'ski'.

[Tristan Croll]

Can't replicate myself now either. *Might* only happen when running in the same session when ISOLDE was installed...? In any case, it didn't actually break the session. Will let you know if I see it again in some reproducible scenario.

[Greg Couch]

Can't reproduce yet.
