Public bug reported:

After importing my certificate from DigiCert into Kleopatra, it
initially shows "Certified", when I click on it to see details, it shows
"invalid".

Kleopatra does not show any further details.

Kleopatra's gnupg log shows the following:

dirmngr[4564.5]: available CRL for issuer ID 
1E0A9BCA80406D19F585298D61F2A132F08E0163 can't be used
dirmngr[4564.5]: command 'ISVALID' failed: Invalid CRL object
dirmngr[4564.5]: DBG: chan_5 -> ERR 167772322 Invalid CRL object <Dirmngr>
gpgsm[51171]: DBG: chan_9 <- ERR 167772322 Invalid CRL object <Dirmngr>

Unfortunately I can't correlate that "issuer ID" to anything in the
certificate chain. Force-disabling CRLs however nicely remediates the
problem and avoids the erroneous "invalid" status.

Overall it's clearly too fragile to consider an end-entity certificate
"invalid" when there's an internal CRL processing bug.
