Ubuntu mate 19.04: random caja and atril crashes (SIGBUS / bus error)

Hi,

I have the latest updates installed. In the past few days, caja and atril have been randomly crashing with SIGBUS / bus error.

Here's a sample output from strace, attaching to the process before it crashed:

poll([{fd=20, events=POLLIN|POLLPRI|POLLOUT}], 1, 0) = 1 ([{fd=20, revents=POLLIN}])
read(20, "22 28 0:21 / /sys rw,nosuid,node"..., 4096) = 3998
read(20, "859 26 0:54 / /run/user/1000 rw,"..., 4194) = 917
read(20, "", 3277) = 0
lseek(20, 0, SEEK_SET) = 0
--- SIGBUS {si_signo=SIGBUS, si_code=BUS_ADRERR, si_addr=0x7f784285a008} ---
+++ killed by SIGBUS +++

How do I debug this further?

Thanks
JP
