Bug 43904 – gpg-agent fails to get passphrase from pinentry-qt

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Benjamin Greiner 2004-03-06 12:02:04 UTC]

When gpg-agent (package newpg) asks pinentry-qt for the passphrase of a gpgkey, for example when using cryptplug with kmail, it fails either on start of pinentry-qt, or on the third letter when entering the phrase.

Reproducible: Always
Steps to Reproduce:
Possibility 1 (general use):
1. be sure to have pinentry-qt (not -gtk) in ~/.gnupg/gpg-agent.conf, gpg-agent running and available for kmail
2. open encrypted pgp/mime message in kmail using cryptplug
3. if window appears try to enter passphrase

Possibility 2 (debug):
1. run `gpg-agent --server --pinentry-program /usr/bin/pinentry-qt --debug-all --verbose`
(or specify these options in gpg-agent.conf)
2. enter passphrase query like 
GET_PASSPHRASE 0A0362A27C73C736C398B22E5DCD494CF357DB02 X X You+need+a+passphrase+to+unlock+the+secret+key+for+user:%0A"Benjamin+Greiner+<[e-mail]>"%0A1024-bit+ELG-E+key,+ID+F357DB02,+created+2002-07-16+(main+key+ID+9CC0B479)%0A
Actual Results:  
A: Get error message about invalid password / can't decrypt email
B: Get error output (see attachment)


Expected Results:  
accepting passphrase and decrypting mail

Current workaround is to use pinentry-gtk instead of pinentry-qt

used package versions:

qt-3.3.0-r1
pinentry-0.6.9
newpg-0.9.4-r1

It appears to be a problem with KDE gui styles. From what i have been able to test, pinentry-qt works with QTs base style but not with some of KDEs own.

Appears to be a KDE issue. Reassigning. 

[Comment 5 Gregorio Guidi (RETIRED) 2005-01-11 11:25:53 UTC]

Is this still happening with pinentry-0.7.x?

No reply from reporter.

Sorry for not replying. Indeed it does work with current version. Thanks.
