If this is indeed an infinite loop, there's at least one cycle in the `threading` map. It would be nice to have access to the raw IMAP log. Without that log, I cannot really do anything. Created attachment 111653 [details]
trojita-connection-log
Now Trojita hangs in infinite loop every time I open mbox. In attachment is log file (some mbox names were anonymized to YYYY). Plus here is backtrace:

(a duplicate bug led me here, so I think that this is a correct report) 1) activate threading 2) open a mailbox 3) perform a search which returns something 4) switch to another mailbox where that search doesn't return anything 5) the threading is still preserved, and trojita assert-crashes: ASSERT: "it != ptrToInternal.constEnd()" in file trojita/src/Imap/Model/ThreadingMsgListModel.cpp, line 1488 (In reply to Jan Kundrát from comment #3) > > 1) activate threading > 2) open a mailbox > 3) perform a search which returns something > 4) switch to another mailbox where that search doesn't return anything > 5) the threading is still preserved, and trojita assert-crashes: > > ASSERT: "it != ptrToInternal.constEnd()" in file > trojita/src/Imap/Model/ThreadingMsgListModel.cpp, line 1488 I cannot reproduce this with my current Trojitá (~git master). So unless someone can reproduce it with a recent version (from git), I suggest we close this. Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days.

For unknown reasons trojita hangs in infinite loop on following place: file trojita/src/Imap/Model/ThreadingMsgListModel.cpp function ThreadingMsgListModel::handleDataChanged 134 while (rootCandidate.parent().isValid()) { 135 rootCandidate = rootCandidate.parent(); 136 } Adding breakpoint on line 137 proved it, while loop is never finished. GUI is completely freezed. What I did? Absolutely nothing, just had opened INBOX and waiting for a new emails. Here is gdb backtrace.
