meld hangs on open for normal user

Running under ubuntu 20.04.

Attempting to open meld as a normal user hangs for 25 seconds on a poll (below excerpt from strace)

15:15:17.997077 poll([{fd=15, events=POLLIN}], 1, 25000) = 1 ([{fd=15, revents=POLLIN}]) <0.000009>
15:15:17.997115 read(15, "\1\0\0\0\0\0\0\0", 16) = 8 <0.000011>
15:15:17.997154 poll([{fd=15, events=POLLIN}], 1, 25000) = 0 (Timeout) <25.001608>
15:15:42.998898 write(15, "\1\0\0\0\0\0\0\0", 8) = 8 <0.000019>
15:15:42.999012 futex(0x2e2b990, FUTEX_WAKE_PRIVATE, 2147483647) = 0 <0.000043>
15:15:42.999190 close(15)               = 0 <0.000067>

Running the same command under sudo there is no delay.

strace output from both commands attached.

  • $ strace -T -tt -o meld.strace meld
