+\r
+The problem is *not* fixed.  \r
+\r
+I was the one who reported this problem two years ago.  I did the\r
+same notmuch search again.  Since I did no know if it's important\r
+with which version the emails were indexed I did a full index\r
+with notmuch 0.17+40~gecbb29e.\r
+\r
+I still have the mbox produced with notmuch show two years ago.\r
+Viewed with mutt (1) I see 206 messages in 7 threads (number of\r
+lines after collapse-all) (notmuch emacs show showed three\r
+threads then).  One of the threads is the one I searched for.\r
+\r
+Today I produced another mbox with the very same command but with\r
+a now larger email corpus freshly indexed with a fresh notmuch.\r
+The mbox contains (according to mutt) 507 messages in 34 threads.\r
+One of them is the thread I searched for.\r
+\r
+I grepped for the 7 subjects within the 34 subjects and only 5\r
+showed up.\r
+\r
+Only 17 of the 507 messages arrived since the problem report two\r
+years ago.\r
+\r
+If somebody want's to dig into this: I can provide the two\r
+mboxes. \r
+\r
+Disclaimer: Many of the emails which arrived before the problem\r
+report are not the exact same than then, because since the I\r
+mangled them with a script.  This should have not changed the\r
+threading but I cannot be 100% sure.  But if it's important for\r
+further investigation I'm probably able to reproduce the status\r
+quo of the email corpus then from my backups.\r
+\r
+Thanks for your persistence. \r
+\r
+Ciao, Gregor\r
