Hi, today I wanted to import a new x.509 cert into kleopatra and it didn't show the pinentry dialog. pinentry-gtk2 was launched and was using 100% CPU but it didn't do anything useful. Just for fun I removed pinentry-gtk2, but then kleopatra immediately complained that it was unable to decrypt the cert. I checked kwatchgnupg and the logs showed a little hint to the problem. gpg-agent[2117.7] DBG: <- GET_PASSPHRASE --data --repeat=0 -- X X Passphrase: Please+enter+the+passphrase+to+unprotect+the+PKCS#12+object. gpg-agent[2117]: starting a new PIN Entry gpg-agent[2117]: can't connect server: ec=4.16383 gpgsm[8945]: gpg-protect-tool: error while asking for the passphrase: No pinentry gpgsm[8945]: error running `/usr/libexec/gpg-protect-tool': exit status 2 gpgsm[8945]: total number processed: 0 gpg-agent[2117]: can't connect to the PIN entry module: End of file gpg-agent[2117]: command get_passphrase failed: No pinentry gpg-agent[2117.7] DBG: -> ERR 67108949 No pinentry <GPG Agent> gpgsm[8945.0] DBG: -> S IMPORT_RES 0 0 0 0 0 0 0 0 0 0 0 0 0 0 gpgsm[8945.0] DBG: -> ERR 50331800 Decryption failed <GpgSM> Looks to me like /usr/libexec/gpg-protect-tool is just choosing the wrong pinentry executable. It should just call /usr/bin/pinentry which should call the correct pinentry-qt4/gtk2/whatever. With pinentry-gtk2 removed, I started pinentry and it called pinentry-qt4. So there are two problems: a) why does pinentry-gtk2 get stuck? b) why isn't pinentry-qt4 called by gpg-protect-tool? Is this working for anyone with kde 4.3.90? Cheers, Andreas
