I found the point where it spends this amount of time. I run

$ truss -o gwenview.tr -d gwenview

and with grep/vim I found the point in time where it waits 25 secs for
something:

...
2.001783437 socket(PF_LOCAL,SOCK_STREAM|SOCK_CLOEXEC,0) =3D 21 (0x15)
2.002053139 connect(21,{ AF_UNIX "/var/run/dbus/system_bus_socket"= ; },33) =3D 0 (0x0)
...
2.019812505 sendmsg(21,{NULL,0,[{"l\^A\0\^A \0\0\0\v\0\0\0\M^H\0\0&quo= t;...,152},{"\^V\0\0\0org.freedesktop.UPower"...,32}],2,{},0,0},M= SG_NOSIGNAL) =3D 184 (0xb8)
27.024832498 poll({ 11/POLLIN 12/POLLIN 21/POLLIN },3,25068) =3D 1 (0x1) 27.024978322 recvmsg(21,{NULL,0,[{"l\^C\^A\^Ac\0\0\0\a\0\0\0m\0\0\0&qu= ot;...,2048}],1,{},0,MSG_CMSG_CLOEXEC},MSG_CMSG_CLOEXEC) =3D 227 (0xe3)
27.025182480 recvmsg(21,0x896a197b0,MSG_CMSG_CLOEXEC) ERR#35 'Resource = temporarily unavailable'

i.e. it sends something to /var/run/dbus/system_bus_socket and waits 25
secs in poll(2) for the answer until it timesout after 25086 millisecs.

=C2=A0 =C2=A0 =C2=A0 =C2=A0 matthias

Tr= y having a look with qdbusviewer and exporting DBUS_SESSION_BUS_ADDRESS if = necessary.
From your log it seems it is accessing org.freedesktop= .UPower the specific method is not shown.

What if = you try to call UPower by hand?

<= /div>
dbus-send --print-reply \ --system \ --dest= =3Dorg.freedesktop.UPower \ /org/freedesktop/UPower \ org.freedesktop.UPowe= r.EnumerateDevices
