[Viplugin-user] Exceptions when closing files

[John E. <jo...@ne...>]

With 0.1.18, everytime I close a file Eclipse gets an exception and
tells me to look at the error log.  I didn't have this problem with
0.1.17.  I'm running Eclipse 2.1.1 on Linux, so maybe that's the
problem.  Anyone else seeing this?

Here's the exception:

!ENTRY org.eclipse.ui.workbench 4 2 Jul 21, 2003 14:04:51.954
!MESSAGE Problems occurred when invoking code from plug-in:
