Package: akregator
Version: 4:17.08.3-1
Severity: important


Dear maintainer,

 after running akregator, just few clicks are allowed before a crash happens.
This issue renders akregator totally unusable for me (sob...).

$ gdb akregator

This problem occurs with both kernel 4.9 and kernel 4.14 on my system.

$ dpkg -l | grep linux-image
ii  linux-image-4.14.0-3-amd64  4.14.13-1  amd64        Linux 4.14 for 64-bit PCs
ii  linux-image-4.9.0-1-amd64   4.9.6-3    amd64        Linux 4.9 for 64-bit PCs
(signed)


I'll provide any further information if needed.

Thanks for your work.
