Comment 26 for bug 1853007

i can confirm this behavior in Linux. i am running same version as reporter on debian unstable (bug 1602759). i would add that those files contain copies of sent emails. sometimes spotted even plain text where the sent email was encrypted. i tried running `thunderbird --verbose` but it did not help revealing more info. i tried `thunderbird -g` but thunderbird-dbgsym seems to be missing from debian.
