I use the Dillo browser and usually when I open a new website I get the following error message:
Dillo HTTPS: Missing issuer certificate!
Unable to get local issuer certificate. The issuer certificate of an untrusted certificate cannot be found.
Sometimes I get this error 3 times in a row while opening bigger websites like Twitter.
If I click Continue the page will load normally.
I've got this problem with Dillo 3.0.5 on FreeBSD 10.3 powerpc (installed from ports) and FreeBSD 10.3 i386 (installed using pkg).
This message however doesn't pop up on Dillo version 3.0.4 on BunsenLabs Linux (Hydrogen) i386.
The source code with this message is available here: https://fossies.org/linux/dillo/dpi/https.c
I thought it might be related to Curl - SSL certificate problem but I've checked the options I installed curl with and
CA_BUNDLE is on.
