I'm seeing the same strace as in comment #12 but with ooimpress version
libreoffice-core/impress-4.2.1.1-1.fc20.x86_64

Not all slide decks trigger it.

strace:

[pid 16718] 1394031255.899177 futex(0x7f387c000910, FUTEX_WAKE_PRIVATE, 1) = 0
[pid 16718] 1394031255.899212 futex(0x7f387c0008e4,
FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 201, {1394031255, 924207000},
ffffffff) = -1 ETIMEDOUT (Connection timed out)
[pid 16718] 1394031255.924292 futex(0x7f387c000910, FUTEX_WAKE_PRIVATE, 1) = 0
[pid 16718] 1394031255.924318 futex(0x7f387c0008e4,
