Changes in Gmail Have Broken Both Plugins

Thanks to those that wrote in reporting this. I can reproduce it and I imagine it is the result of an interface change in Gmail. I hope to have a patch out soon.

Update:
I've located the problem and have a patch that seems to work. I will try to get new versions of the plugins out this weekend. You can read about the details here

Update 2 I have just finished installing Leopard on my test machine and have verified that both plugins fail to properly send emails. The good news is that the latest CVS version of libgmailer seems to resolve both issues... I still need to do some more testing.

Update 3 It appears this was not a Leopard-specific bug, but rather a result of Gmail's transition to new UI and javascript.
