MASTER Key management / Recipient Key Selection broken (endless loop in EnigConvertToUnicode)

I can confirm this bug.

mozilla-thunderbird 1.5.0.12-0ubuntu0.7.04
mozilla-thunderbird-enigmail 0.94.2-0ubuntu1
gnupg 1.4.6-1ubuntu2

what does openpgp -> About dialog show you?

It shows this:

It shows the same to me (in german) :

Hi,

I've also got the same problem. I didn't know that this was already addressed and did open a new one; 121352.

Cheers,
Rob

I created a new profile (mozilla-thunderbird -P) and set it up with a different POP3 email account. I was able to send and receive plain text and encrypted email, but the Key Management window brought up the same error as before.

Two other observations:

1. A few seconds elapses between opening the Key Management window and getting the error message. During this time mozilla-thunderbird-bin uses 100% CPU.
2. If I create a new user account on the same machine, it all works OK.

this bug is known to enigmail developers though the cause is not known. I will attach the patch for enigmail soon.

though probably caused by tbird in the first, place we will fix this on enigmail side.

It seems to me it has something to do with certain characters being present in the names of people in the keyring. At least, I can provoke this by adding swedish national characters in the "real name" of people owning keys in my ring - åäöÅÄÖ etc. Also, it might be something with the encoding - UTF-8 vs. ISO8859-1 - perhaps something about the encoding in the keyring being different than the current TB/EM one? Just guessing, sorry.

sbg, you are right. I had a "broken" é in one of the names of the keys in my keyring. When I removed it, everything works again. There is still one keyname wit an ü in it and one with a "broken" ä, that don't cause any problems.
Thanks for your "guess"!

I can confirm this. I deleted the one key on my keyring that contains non-Latin characters (a Chinese name with a .tw address) and now Enigmail's key management works again. Thanks to sbg and anke for the tip.

Indeed, also conformation from my side, removing the key with a È did help.

Installing the latest update of enigmail fixes it for me.

I ran
sudo thunderbird
to have write access to the plugin dirs and then
extra/extentions/update

updated enigmail to 0.94.4 or so for me which fixes the bug.

Would be nice if this was made available via apt.

... all three uploaded to -proposed.

Please make this bug conformant to https://wiki.ubuntu.com/StableReleaseUpdates. Wrt. the edgy patch, the changelog talks about "FTBFS in dapper". Is that still relevant for the edgy update?

Is this bug fixed in gutsy? How was it tested? This is quite a big patch, so it should be confirmed to be fixed and not causing regressions in gutsy.

Martin, I added the required infos to summary ... gutsy package isn't affected because it ships latest enigmail ... which doesn't have this problem.

The patch replaces the Unicode functions with the ones from latest enigmail. It was prepared by enigmail author and even released officially in 0.94.3 iirc.

Alex claims this to be fixed in gutsy.

Accepted to dapper-proposed.

Accepted into feisty-proposed.

"Wrt. the edgy patch, the changelog talks about "FTBFS in dapper". Is that still relevant for the edgy update?"
