Comment 26 for bug 1265898

@Ryan Sipes: have others in fact now tested the ostensible fix? I feel that this bug report - and indeed mine (#1593578), which at present remains open - should be closed only if there has been a fair amount of testing. (I hesitate myself to test. Here is why. When I have installed nightly versions of Thunderbird it has caused problems with my main Thunderbird installation. Yet perhaps that happened only on Windows. If so I could try a nightly version of Thunderbird at least if I could get it as an appImage or similar.)
