This was with the following RPM versions:
xfce4-mailwatch-plugin-1.2.0-8.fc24.x86_64
xfce4-panel-4.12.0-5.fc24.x86_64

From the source (https://git.xfce.org/panel-plugins/xfce4-mailwatch-plugin/tree/libmailwatch-core/mailwatch-mailbox-imap.c?id=3ed2f006ff16b0412f00beb3a8b05d25090c9055) it looks like it might be returning after a "buffer full" error.
