Bug ID: 391718
Summary: Trojita hangs in infinite loop
Product: trojita
Version: git
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Other
Assignee: trojita-b...@kde.org
Reporter: pali.ro...@gmail.com
Target Milestone: ---
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.

Apparently I cannot debug it as gdb cannot resolve inlined function :-(
