The problem appears to be at irqlist.c:49 or so:
sprintf(buf, "/proc/irq/%i", number);
dir = opendir(buf);
do {
entry = readdir(dir);
I'm assuming that the readdir on a failed opendir is the problem here,
although I haven't attached a debugger. The obvious fix is just to make
the do loop conditional on the opendir succeeding - I'll give it a shot
tonight and let you know.
Cheers,

Description:
irqbalance - Daemon to balance interrupts for SMP systems
Closes: 517183
Changes:
irqbalance (0.55-2.4lenny1) stable-proposed-updates; urgency=low
.
* Non-maintainer upload.
* On at least sparc, the kernel presents the timer as IRQ 0, but does not
provide a /proc/irq/0 for irqbalance to manage. Ignore IRQs that do not
have a /proc/irq/<n> entry, since we can't manage them, instead of
ignoring the opendir failure and attempting to carry on. (closes: #517183)
