UnsupportedOperationException in subversive synchronize view
I double clicked on a scala file in the subversive "synchronize view" and the scala editor throws an exception. The same file opens without problem in the scala perspective.
This is scala 2.8.0 on Helios
eclipse.buildId=I20100608-0911
java.version=1.6.0_20
java.vendor=Apple Inc.
BootLoader constants: OS=macosx, ARCH=x86_64, WS=cocoa, NL=en_US
Framework arguments: -product org.eclipse.epp.package.java.product -keyring /Users/acozzi/.eclipse_keyring -showlocation
Command-line arguments: -os macosx -ws cocoa -arch x86_64 -product org.eclipse.epp.package.java.product -keyring /Users/acozzi/.eclipse_keyring -showlocation
