More detail: It happened when I download HTML Preview plug-in. But it cannot display HTML file and throw this exception.
According to the code this might happen only if browser editor is already disposed. Have you closed/reopened tabs/project, etc?
Seem it happens when I switch to Text tab too fast. When it is finished to download, it hung a little and I clicked Text tab. I met this problem several times.
