[Sugar-devel] [PATCH Browse] Handle LoadInterruptedByPolicyChange SL #3972

[Manuel Kaufmann]

This error is raised when the mimetype policy suffers a change. When
this happens __load_error_cb is called and we were showing the error
page in any case.

With this patch that case is properly handled in __load_error_cb and
the error page is not shown on the current tab. In fact, we keep the
same page where the user clicked the link in the tab.
