Dropbox logs out after every reboot

[BjornSkjaerpe]

Hello there,

I've updated to OS X 10.9.5, and then I took interesting issue: every time I log into the system my Dropbox asks me to log in.



Every time I log in, and every time it starts to indexing my whole Dropbox folder. That's very annoying, because my Dropbox folder is ~50 Gb. Sometimes it duplicates some files or makes conflict copy. Sometimes it good after indexing, but every single time I need to wait until indexing ends to operate with the Dropbox comfortably.



That's very-very annoying. I'm asking, because my MacBook Pro is working well, without any kind of problems with the same Dropbox version (v2.10.30) and with the same OS X (10.9.5) version.


When I'm going to Dropbox' https://www.dropbox.com/account#security page I see that it relinks my PC as a new hardware!




And I noticed that my iTunes starts to indexing something every time it starts:




And I'm not sure it refers to this, but sometimes when I'm logging in I'm facing with this Kernel Panic message:



Anyone faced with the similar?
Thanks.

P. S. My configuration should be somewhere here in the signature.

Same situation here with Yosemite 10.10.3

Repair permission does nothing and each time I login to OS X the Dropbox screen asking credentials appears.

Anybody know how to resolve this issue?
