[Users] CM goes unresponsive...

[Pierre Fortin]

Hi,

Been noticing some weird delays recently where switching from one message
to another in the same folder takes many seconds.  When this happens, I
also see a cursor consisting of 2 circles rotating around each other.

Today, I'm seeing just total hangs for 30 seconds when switching between
messages; even back to a message that was just opened prior to the
current one.

Attached strace and dead silence until the 30 seconds is up...  here's a
sample output:

Since some files appear to be in the picture, they contain: 

/etc/resolv.conf:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by
resolvconf(8) #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN 
nameserver 192.168.1.1
nameserver 8.8.8.8
search pfortin.com

/home/pfortin/.claws-mail/avatarcache/a016bc8af5d2b254f73392180a641af5:
--- no such file

/etc/hosts:

Anyone else seeing weird, unexplained delays?
