Rip, I am in no way a submarine enthusiast/expert. I can only make some comments based on the info from Russian Underwater Fleet website.
Here is a page about accidents and catastrophes in Underwater Fleet since the War ended. It includes many diesel sub accidents too.
http://submarine.id.ru/memory.shtmlOk, let's start.
Soviet K-129 Western Pacific (this was a Golf class we tried to raise) - Loss of all hands K-129 was a diesel missile sub. Sank on March 8th 1968, reason unknown. Versions: probable snorkel valve malfunction was an official Soviet one, American version was an explosion, reported by an acoustic station near Hawaii. Though, most reasonable version is a collision with SSN-579 Swordfish, that returned to base in Okinawa with very recognizable damabe to the "sail" (or better to say "conning tower"?). Anyway, Americans knew the position quite well.
Soviet K-8 NE Atlantic - Loss of all hands K-8 was lost because of a fire on April, 12, 1970. Of 125 crew members 52 were lost. K-8 was the third Soviet nuclear sub, in service since 31.12.59. An accident happened on the 52nd day of autonomous mission, practically the limit for project 627.
Soviet Komsomolets (Mike class) Norwegian Sea - can't remember death toll - I think about 40. Sub sank. K-278 story is well known

Of the 69 crew members 39 perished... One sailor survived in an evacuation camera from the depth of 1500m...
Soviet Echo I/II that lost a game of chicken against the US 6th fleet in the Med in the 70s. 10 - 12 killed by rocket fuel oxidizer fumes after collision Couldn't find anything about this accident. Probably a legend.
Soviet ballistic missile submarine that surfaced, burning, SE of Florida in the early 1990s I think - unknown dead Must be K-219, project 667AU (Nalim), lost on October, 6th, 1986, 4890 miles NE from Bermuda islands. Fire in the missile silos, probably a result of a collision with an American sub. 6 crew members lost. I think we can say that last two episodes are actually one.
Russian Kursk Barents Sea - loss of all hands
Soviet K-19 - two incidents - more than 40 killed
Enough said about this two...
Now - some stats.

In 1986 USSR had 364 subs, of whom:
76 had ballistic missiles (62 nuclear)
64 had antiship cruise missiles (50 nuclear)
218 had torpedo-only armament (73 nuclear)
Other Warsaw Pact countries had only 6 subs - 3 Poland and 3 Bulgaria
It gives us 370 boats total.
USA had 139 subs, including 38 missile subs, 97 attack subs, few special boats and 4 diesel, out of combat duty.
Other NATO countries had 153 subs, including 18 British and 11 French nuclear boats.
Japan has 14 diesel subs and Australia has 6.
This gives us 312 boats total.
Production numbers for USSR and US since early 50s:
USSR: 235 nuclear and 300 diesel.
USA: 150 nuclear and 18 diesel.
Accident ratio:
USSR: 6 subs lost out of 535, gives us 1 boat lost per 89 built.
USA: 5 boats lost out of 168 built, gives us 1 boat per 33 built.
The worst accident ratio belongs to France: 5 subs lost out of 35 after the War.
