KDevelop using 100% of CPU all the time

Hello,

KDevelop (5.1.1) on my Ubuntu (14.04.5 64 bits) is using 100% of one of my
core all the time. The project I'm working on is pretty big so it takes a
bit of time to load / parse everything, which is understandable. However,
KDevelop keeps using all the CPU even when the parsing is done (no task
window in the bottom right corner). Even after several hours, it keeps
using 100% of the CPU.

After attaching strace, I can see that it apparently loops on a poll:
poll([{fd=33, events=POLLIN}, {fd=23, events=POLLIN}, {fd=36,
events=POLLIN}, {fd=55, events=POLLIN}, {fd=11, events=POLLIN}, {fd=28,
events=POLLIN}, {fd=7, events=POLLIN}], 7, 0) = 0 (Timeout)
poll([{fd=33, events=POLLIN}, {fd=23, events=POLLIN}, {fd=36,
events=POLLIN}, {fd=55, events=POLLIN}, {fd=11, events=POLLIN}, {fd=28,
events=POLLIN}, {fd=7, events=POLLIN}], 7, 0) = 0 (Timeout)
poll([{fd=33, events=POLLIN}, {fd=23, events=POLLIN}, {fd=36,
events=POLLIN}, {fd=55, events=POLLIN}, {fd=11, events=POLLIN}, {fd=28,
events=POLLIN}, {fd=7, events=POLLIN}], 7, 0) = 0 (Timeout)

Has anyone experienced the same issue / has an idea about how to fix that?

Thank you so much!

Ben
